When viewing the attached PDF in XPDF, libfontconfig segfaults trying to fill in the non-embedded fonts. I have filed a bug upstream with fontconfig (because it shouldn't segfault at all), but Poppler is probably calling the library improperly in the first place. Here's the stack trace: #0 0xb76a1832 in FcConfigSubstituteWithPat () from /usr/lib/libfontconfig.so.1 #1 0xb76a1f35 in FcConfigSubstitute () from /usr/lib/libfontconfig.so.1 #2 0xb7ed5dbb in GlobalParams::getDisplayFont () from /usr/lib/libpoppler.so.2 #3 0xb7e89eeb in SplashOutputDev::doUpdateFont () from /usr/lib/libpoppler.so.2 #4 0xb7e8a1ac in SplashOutputDev::drawChar () from /usr/lib/libpoppler.so.2 #5 0xb7eafa4b in Gfx::doShowText () from /usr/lib/libpoppler.so.2 #6 0xb7eb04d6 in Gfx::opShowSpaceText () from /usr/lib/libpoppler.so.2 #7 0xb7ead3f1 in Gfx::execOp () from /usr/lib/libpoppler.so.2 #8 0xb7ead5ba in Gfx::go () from /usr/lib/libpoppler.so.2 #9 0xb7eadb43 in Gfx::display () from /usr/lib/libpoppler.so.2 #10 0xb7ef34d6 in Page::displaySlice () from /usr/lib/libpoppler.so.2 #11 0xb7ef59c7 in PDFDoc::displayPageSlice () from /usr/lib/libpoppler.so.2 [... xpdf functions removed ...]
Created attachment 12652 [details] file that causes segfault when viewed in xpdf
Upstream bug (in libfontconfig): https://bugs.freedesktop.org/show_bug.cgi?id=13321
I can't reproduce the crash with evince.
Here's another PDF which gives this crash (I'll give a link instead of attaching it, because it is quite large): http://vanveelen.xs4all.nl/documenten/gramcord.pdf Here's my stack backtrace: Program received signal SIGSEGV, Segmentation fault. 0xb7628558 in IA__FcConfigSubstituteWithPat (config=0x3ff00000, p=0x81551c8, p_pat=0x0, kind=FcMatchPattern) at fccfg.c:1296 1296 fccfg.c: No such file or directory. in fccfg.c Current language: auto; currently c (gdb) bt #0 0xb7628558 in IA__FcConfigSubstituteWithPat (config=0x3ff00000, p=0x81551c8, p_pat=0x0, kind=FcMatchPattern) at fccfg.c:1296 #1 0xb7628be5 in IA__FcConfigSubstitute (config=0x3ff00000, p=0x81551c8, kind=FcMatchPattern) at fccfg.c:1512 #2 0xb7e4e1cb in GlobalParams::getDisplayFont (this=0x8089008, font=0x811fbb0) at GlobalParams.cc:1089 #3 0xb7e02e6b in SplashOutputDev::doUpdateFont (this=0x80e3ca0, state=0x812d5f0) at SplashOutputDev.cc:999 #4 0xb7e0312c in SplashOutputDev::drawChar (this=0x80e3ca0, state=0x812d5f0, x=<value optimized out>, y=<value optimized out>, dx=7.1999999999999993, dy=0, originX=0, originY=0, code=49, nBytes=1, u=0xbfd419fc, uLen=1) at SplashOutputDev.cc:1277 #5 0xb7e27d0b in Gfx::doShowText (this=0x8119218, s=0x8139190) at Gfx.cc:3290 #6 0xb7e28adf in Gfx::opMoveShowText (this=0x8119218, args=0xbfd41b24, numArgs=1) at Gfx.cc:3097 #7 0xb7e255d1 in Gfx::execOp (this=0x8119218, cmd=0xbfd41cb0, args=0xbfd41b24, numArgs=<value optimized out>) at Gfx.cc:726 #8 0xb7e2579a in Gfx::go (this=0x8119218, topLevel=1) at Gfx.cc:594 #9 0xb7e25d23 in Gfx::display (this=0x8119218, obj=0xbfd41d8c, topLevel=1) at Gfx.cc:557 #10 0xb7e6b8d6 in Page::displaySlice (this=0x8106d18, out=0x80e3ca0, hDPI=81.235154394299286, vDPI=81.235154394299286, rotate=0, useMediaBox=0, crop=1, sliceX=0, sliceY=0, sliceW=671, sliceH=950, printing=0, catalog=0x80ff248, abortCheckCbk=0, abortCheckCbkData=0x0, annotDisplayDecideCbk=0, annotDisplayDecideCbkData=0x0) at Page.cc:406 #11 0xb7e6ddc7 in PDFDoc::displayPageSlice (this=0x80fe828, out=0x80e3ca0, page=1, hDPI=81.235154394299286, vDPI=81.235154394299286, rotate=0, useMediaBox=0, crop=1, printing=0, sliceX=0, sliceY=0, sliceW=671, sliceH=950, abortCheckCbk=0, abortCheckCbkData=0x0, annotDisplayDecideCbk=0, annotDisplayDecideCbkData=0x0) at PDFDoc.cc:396 #12 0x0805d65c in PDFCore::needTile (this=0x80e3660, page=0x8119118, x=0, y=0) at PDFCore.cc:835 #13 0x0805ffd7 in PDFCore::update (this=0x80e3660, topPageA=1, scrollXA=0, scrollYA=0, zoomA=-1, rotateA=0, force=1, addToHist=1) at PDFCore.cc:658 #14 0x08064267 in XPDFCore::update (this=0x80e3660, topPageA=1, scrollXA=0, scrollYA=0, zoomA=-1, rotateA=0, force=1, addToHist=1) at XPDFCore.cc:285 #15 0x0805b500 in PDFCore::displayPage (this=0x8154e60, topPageA=1, zoomA=-1, rotateA=0, scrollToTop=1, addToHist=1) at PDFCore.cc:292 #16 0x0806fd20 in XPDFViewer (this=0x80c20c0, appA=0x8096650, fileName=0x80c2098, pageA=1, destName=0x0, fullScreen=0, ownerPassword=0x0, userPassword=0x0) at XPDFViewer.cc:297 #17 0x080618ce in XPDFApp::open (this=0x8096650, fileName=0x80c2098, page=1, ownerPassword=0x0, userPassword=0x0) at XPDFApp.cc:228 #18 0x08072208 in main (argc=Cannot access memory at address 0x1 ) at xpdf.cc:311 #19 0xb794c838 in __libc_start_main () from /lib/libc.so.6 #20 0x080518e1 in _start () This is fontconfig 2.4.2, compiled on Gentoo.
works here on fontconfig 2.4.2 too, not gentoo though
gentoo developer acknowledged it's a gentoo problem
OK, can you provide the bug number on http://bugs.gentoo.org/ ? (Or privately bring me into contact with the gentoo developer you mention?)
no, sorry i can not point you to gentoo bugtracker. gentoo developer nick is genstef
For reference, the Gentoo bug for this is http://bugs.gentoo.org/show_bug.cgi?id=199827 . It has been fixed in the most recent release.
