Seems like -march=athlon-xp is the culprit!

*** Bug 122199 has been marked as a duplicate of this bug. ***

you are saying that "-march=athlon-xp -O2 -pipe" bails too?

could you paste the error with those flags? thanks

Hmm, weird I was wrong... There must be the combination itself... 
CFLAGS = CXXFLAGS = "-ftracer -ffast-math -march=athlon-xp -fomit-frame-pointer
-pipe -mfpmath=sse -fvisibility-inlines-hidden" compiled nice. Adding -O2 broke
it! :/

Removing -ftracer helped!!!

LOL, it segfaulted on runtime... Why am I not suprised? ;)

never mind Comment #6, it was due to some permissions probably.

what CFLAGS do you now successfully use?

"-O2 -ffast-math -march=athlon-xp -fomit-frame-pointer -pipe
-mfpmath=sse -fvisibility-inlines-hidden"

no love with the initial -O3 ?

-O3 is replaced by -O2 by the ebuild, so I donnu how well it performs with -O3.

-march=athlon-xp -O2 -pipe -fomit-framer-pointer -ftracer  <--- this exhibits
the same error for you?

-fomit-frame-pointer of course

yepp, -ftracer is definetly the culprit in this drama.

fixed ebuild should show in 2 hours, sync and emerge
thanks for reporting
