Good day,
I have been messing around with my gentoo systems. After I upgraded from
Freetype 2.1.7 to 2.1.9 mozilla and firefox started segfaulting when
accessing certain sites. It appears to make no difference to which
release the application was build. Firefox linux binaries from
mozilla.org also are affected. Not only mozilla seems to be affected,
the gnome font viewer also went down accessing specifically pcf fonts. I
traced down this is also what takes mozilla down.
Reverting freetype to 2.1.7 stabilised everything.
I went on the trial and error way in the hope to find which specific
commit between 2.1.7 and 2.1.9 that introduced this and came up with the
follwing commit:
http://cvs.freetype.org/cgi-bin/viewcvs.cgi/freetype2/src/pcf/pcfdrivr.c.diff?r1=1.7&r2=1.8
If I revert this patch from 2.1.9 things appear stable, however i'm not
experienced enough with C to judge what side effects reverting this
patch have.
My experience with pcf fonts are confirmed by the distro bug report at
http://bugs.gentoo.org/show_bug.cgi?id=57796
Ironically bugs.gentoo.org itself makes mozilla request one of helv* pcf
fonts on the system and goes down ;)
I hope this gives enough information, if not i will try to provide more.
I subscribed to the list, so ideally i should receive replies send here ;-)
