The development versions of gimp segfaults while loading fonts when it's compiled with the -Os flag. I suggest a 'filter-flag -Os' line is added to the ebuild. The protection against overoptimisation (which is now commented out) seems to be a good idea, though I don't know whetver changing -Os to -O2 will work. Filtering -Os out does work (at least for me).
Please post emerge info, what CFLAGS did you build with ? What gcc version etc.

Please build with sane CFLAGS, something like: CFLAGS="-march=i686 -O2 -pipe" emerge gimp
Ok, here are the results: -march=i686 -O2 -pipe: works -O2 -s -mcpu=athlon-tbird -march=athlon-tbird -mmmx -m3dnow -pipe -fomit-frame-pointer -fforce-addr: doesn't work. Maybe it would be a good idea to filter out any O-flags when -mcpu and -march are set to athlon-tbird? Or just change athlon-tbird to i686?
As far as I know -mmmx and -m3dnow is not required since it's already part of -march=archtype. I agree that it is a good idea to force sane cflags on bigger projects.
I try to emerge gimp-2.0_pre2 with CFLAGS="-march=i686 -O2 -pipe" on my machine (Athlon XP), but without luck. A segfault occur while loading the fonts.
Perhaps it would be best to just have -O2 and -Os replaced with -O1 in the ebuild..
I don't think so, it's probably some other flag causing this. I can build it just fine with any of the Ox's . @comment 6 , will lowering your optimizations make it work or is it another problem altogether ?
Update: gimp-2.0_pre3 works fine with my flags from comment 2. But I'd wait at least till next version before closing this bug. I remember that one of the 1.3.x versions worked too, but the next release had problems again.
Well i won't wait, reopen if you actually have problems.
