Cedric, were you able to reproduce this? Could it be this is related to the toolbar docking crash? WinLin, do you have the table toolbar docked, or floating?

Cedric: confirmed. put cursor into first paragraph of second page. Could you have a look please?
(In reply to comment #3) > Cedric, were you able to reproduce this? Could it be this is related to the > toolbar docking crash? WinLin, do you have the table toolbar docked, or > floating? I have the table toolbar floating. Here is the screenshot : https://bugs.freedesktop.org/attachment.cgi?id=39874 My friend found this problem happened only when using the following chinese truetype font: http://cle.linux.org.tw/fonts/cwttf/center/cwheib.ttf If clicking on the yellow area did not freeze writer, type something on there might make it. Thank you.
Dear all, This problem still bother me when using Libreoffice 3.4 beta4. Would you fix this prolem please? Thank you so much.
I package the font and odt into a 7-zip file: https://bugs.freedesktop.org/attachment.cgi?id=60648 This bug is annoying to me for 2+ years, I lost lots of data again and again, please help me. I found the download link of the truetype font was broken, so I package the font and odt into a 7-zip file. (Don't worry, the font is licensed with GPL.) If you need any information about this bug, please let me know, I will do my best to test it. Thank you~
This is a Writer bug, right?! Therefore changed 'Component'.
Hi~ Roman Eisele: Thanks for your help. I also change the version to 3.5.3, because I found Writer of version 3.5.3 still crashed due to this bug.
@winlin0330: > I also change the version to 3.5.3, because I found > Writer of version 3.5.3 still crashed due to this bug. Thank you for your help. But I'm afraid to say that the version field should contain the number of the FIRST version which is known to contain the bug, not the last one. So, could you please change the version field to the first version in which you found that bug? Is it 3.3.0 release? Thank you very much! First idea: I wanted to check first if the bug has something to do with some corruption of the font file ('cwheib.ttf'). But Apple's FontBook did not find any errors in this font, and FontLab 5.0.4 opens the font file without any problems. So the font seems OK.
REPROCUBILE with LibreOffice 3.5.3.2 (Build-ID: 235ab8a-3802056-4a8fed3-2d66ea8-e241b80), German UI installed, on MacOS X 10.6.8. I will attach the MacOS X log file. Reproducible also on MacOS -> changed Platform to 'All'. Observations: 1) There is no influcene of the Table toolbar status to the freeze -- the freeze occurs both when the toolbar is floating and when it is docked. 2) But I can reproduce the freeze ONLY when and if the font 'cwheib.ttf' is installed. If I de-install it again, NO freeze occurs, I can even edit the yellow text 'CLICK HERE WILL FREEZE WRITER'. Therefore, although the font file is not damaged, corrupted, invalid etc. (see my comment #11), this font definitely has some influcene on the problem.

Dear Roman Eisele: Version before 3.4.6 is not available to download, but I can reproduce this bug on OpenOffice.org 3.3.0, I think this bug may be inherited from OpenOffice.org. Should I test any earlier version of OpenOffice.org? A difference should be noted, in OpenOffice 3.3.0., click " CLICK HERE WILL FREEZE WRITER " won't freeze Writer, but typing any character in that yellow area still freeze Writer. Additionally, using other chinese truetype font sometimes meet this bug, it occurs while inserting some chinese words in page one. But it's hard to find the way to reproduce so far. Roughly, I think this problem involved: (1) a table splits across pages; (2) a table cell contains chinese characters, some paragraphs in the table cell go across pages. Thank you.

Thank you very much for testing! > Should I test any earlier version of OpenOffice.org? No, for now it is sufficicent to know that this bug is present since 3.3.0 and may be interited from OOo. -> We set the Version field to the oldest available version (3.3.0b2) to indicate this. > A difference should be noted, in OpenOffice 3.3.0., click " CLICK HERE WILL > FREEZE WRITER " won't freeze Writer, but typing any character in that yellow > area still freeze Writer.

This sounds very reasonable to me.
On pc Debian x86-64 with 3.5 sources updated some days ago I don't reproduce the pb. (I installed the font by following these steps in root mode: - cp <download directory>/cwheib.ttf /usr/local/share/fonts - fc-cache -r ) Did I miss anything during font install? Then I: - clicked on the catchphrase - double clicked on a word then several words of this catchphrase - type something inside it nothing special, no specific logs on console. Anyone to retest on newer LO version (3.5.5 or 3.6.0)?

Hi~Julien Nabet: I am happy to hear that this bug is possible solved. But when I tried 3.6.0(downloaded from official site of Libreoffice), Writer was still freezed when I scrolled down and clicked the yellow area. Would you check cwheib.ttf is successfully installed? If cwheib.ttf is installed: (1) you will find "cwTeX粗黑體" in the fonts list of Writer, and (2) you can see "cwTeX 粗黑體" after you execute command " fc-list | grep cw" in terminal. (3) you will see the odt file is looked like this: https://bugs.freedesktop.org/attachment.cgi?id=65725 Note: Would you try to install the cwheib.ttf to ~/.fonts and restart Libreoffice to try it again? If you are using Libreoffice that come from Debian repository, remember to close the quickstarter for ensuring Libreoffice is "really" restarted. Thanks for your testing~
Thank you for your feedback winlin. Sorry for my mistake, I reproduced the problem with master sources. In fact the link http://cle.linux.org.tw/fonts/cwttf/center/cwheib.ttf is broken. I installed the Debian package fonts-cwtex-heib and runned fc-list, # fc-list | grep cw /usr/share/fonts/truetype/cwtex/cwheib.ttf: cwTeX 粗黑體,cwTeXHeiBold:style=Medium Noticed on console, this log repeated endlessly: warn:legacy.osl:11193:1:/home/julien/compile-libreoffice/libo/sw/source/core/text/frmform.cxx:298: SwTxtFrm::CalcFollow: cheesy follow
Also still REPRODUCIBLE with MacOS X: LibreOffice 3.6.1.1 (Build ID: 4db6344), German langpack installed, on MacOS X 10.6.8 (Intel), still freezes when I click the words "CLICK HERE WILL FREEZE WRITER", if and only if the font 'cwheib.ttf' is installed.
@Caolán: This long-standing issue seems related to font handling: I can reproduce the freeze only if the font 'cwheib.ttf' is installed. I insert you into the CC list because you have fixed many font-related bugs. Maybe you could take a look at this issue? This would be very much appreciated! Thank you very much in advance!
Created attachment 65727 [details] bt on master on console trace If it can help, I attached bt from console trace.
From bt, I tried to compare the paths used, so I put a break frmform.cxx:576 (SwTxtFrm::FormatAdjust) and click each time just in front of "C", the first letter of catchphrase to be in exactly the same conditions. When the font isn't used: it never enter in this if: 208 if( !pMyFollow->GetOfst() || pMyFollow->GetOfst() != nTxtOfst || 209 bFollowFld || pMyFollow->IsFieldFollow() || 210 ( pMyFollow->IsVertical() && !pMyFollow->Prt().Width() ) || 211 ( ! pMyFollow->IsVertical() && !pMyFollow->Prt().Height() ) ) pMyFollow->GetOfst() = 88 and nTxtOfst = 88 and all the cond are false so we don't enter in the if and so SwTxtFrm::CalcFollow isn't called When the font is used: it enters in the if as soon as first time pMyFollow->GetOfst() = 0 nTxtOfst = 137 I'll try to dig more but I must recognize I don't know the meaning of all that.
Created attachment 66038 [details] The second file that freezed Writer. Dear all: I uploaded the second and third file (freeze2.odt and freeze3.odt) that would freeze Writer. In freeze2.odt, delete the red area and click the yellow area, you will see a freezed Writer. Please take a look at the Paragraph 7 on page 3. There is only one line in table on page 3 after you deleted the red area of Paragraph 6, the "only one line in table on page 3" may make Writer get into the loop of creating and deleting a new page for the large table. I guess this is why Writer freezed. On the other hand, the file freeze3.odt show us a different example. The freeze3.odt had no page3, but if you add any character in Paragraph 6 or Paragraph 7 to make a new line for pushing Writer to creat page 3, Writer will freeze. In freeze2.odt and freeze3.odt, we all see the "only one line in table on page 3" make Writer freeze. So I guess this maybe a problem of table behavior. But I think this may involve something wrong about chinese (or CJK) paragraph dealing mechanism in table, because I only meet this problem when I typing Chinese characters in a very long table ( and this table must goes across many pages). Thanks a lot~
Created attachment 66039 [details] The third file that freezed Writer.
On pc Debian x86-64 with master sources updated today, I gave a try to first file, we still have the same.
Hi Julien: Thanks so much for helping to debug this; I guess it's a layout loop - but ... ;-) anyhow - the best way to find where something is hanging in gdb is (after breaking) to type: 'finish' repeatedly until it hangs - then you know it hung in that method. Then break it again, and go up to that method and get the states of all the variables you can find in that loop. Thanks anyhow ! :-)
