Description Emopig 2009-01-10 21:40:33 UTC
There is a small memory leak in fontconfig, patched on the mailing list here:
http://lists.freedesktop.org/archives/fontconfig/2008-November/003032.html

Reproducible: Always

Steps to Reproduce:




I just spent 45 mins tracking down a memory leak to find it had already been identified and patched. There hasn't been a fontconfig release since May and no commits to the GIT repository since June so I figured the ebuild might as well be bumped to include this patch?

http://lists.freedesktop.org/archives/fontconfig/2008-November/003032.html

I had a valgrind backtrace of a memory leak reaching this function but i foolishly overwrote the log file, here is a snippet from an earlier log, I was running valgrind on GNOME applets, in this case specifically the system monitor applet.

==9105== 80,672 (32,512 direct, 48,160 indirect) bytes in 45 blocks are definitely lost in loss record 221 of 225
==9105==    at 0x4C22E21: realloc (in /usr/lib64/valgrind/amd64-linux/vgpreload_memcheck.so)
==9105==    by 0xBD4AD02: (within /usr/lib64/libfontconfig.so.1.3.0)
==9105==    by 0xBD4B794: (within /usr/lib64/libfontconfig.so.1.3.0)
==9105==    by 0xBD48221: FcFontRenderPrepare (in /usr/lib64/libfontconfig.so.1.3.0)

I have tested the patch and the leak vanished.

Please, read this discussion till the end. You'll find that upstream don't have any intentions to apply this patch as patch is broken.
