testcase

The attached document crashes LibreOffice under Linux when Graphite is not disabled (SAL_DISABLE_GRAPHITE=0 ./soffice).

I have also prepared a small test file (without crash) with a strange Graphite regression, missing superiors in a commonly formatted paragraph.

testcase 2

The content.xml of the ODF contains plain, continuous text: 

<text:p text:style-name="P1">Hatodikos voltam 1986-ban, amikor vakáció előtt pár nappal az osztályfőnököm egy, akkor még ritkaságnak számító személyi számítógépet mutatott be az osztálynak az utolsó matematikaórán. Az első találkozás hatására a nyári szünetben – ugyan</text:p>

But there is a regression in its Graphite layout, mixed normal and superior text (see screenshot). LibO Version 3.6 alpha0 works well this test file.

Crash not reproducible for me with LO 3.6.0.0.beta2 under Ubuntu 11.10 x86_64 with gnome-shell.
In your testcase_2 you have a line spacing of 75%. Is it intended ?
I do not reproduce your horrible screenshot. ;-)

Best regards. JBF
Comment 4 László Németh 2012-07-05 02:06:28 UTC 
It seems, this is a Graphite bug resulting problem and crashes only on 32-bit platforms (I have specified the platform in the bug report.), but it should be confirmed. Thanks for your testing.
Comment 5 László Németh 2012-07-05 03:08:15 UTC 
(In reply to comment #3)
Yes, 75% is intended for this superscript letters, but it is not relevant to the bug. (By the way, default "single" line spacing of LibreOffice is 115% of the letter size, so 87% proportial value is the "real" single line spacing.)
Comment 6 Andras Timar 2012-07-06 04:29:04 UTC 
It does not crash under Windows (32-bit).
Comment 7 László Németh 2012-07-06 05:53:20 UTC 
It seems, this is a (significant. I have tested with several test file) problem of my platform/configuration/temporary files. Starting LibreOffice as root, solves this and other Graphite problems (eg. crashing with Graphite feature name of Linux Libertine G.) Many thanks for your tests.

Comment 9 László Németh 2012-07-06 06:23:31 UTC 
Solution: Using Graphite extension (https://github.com/thanlwinsoft/groooext), the program set the Graphite cache size in ~/.profile

export SAL_GRAPHITE_CACHE_SIZE=2047

Removing this line the problem has been solved.
