This is btw the first time I am using gdb ever so bear with my blind poking around :) For the sake of comparison I repeated the above session without "return 0" to show that it does not work: entropy bin # gdb gimp GNU gdb 5.3 Copyright 2002 Free Software Foundation, Inc.

hmm .. can you try compiling gimp with FEATURES="nostrip" CFLAGS="-march=pentium3 -O1 -pipe -g" emerge gimp and then run it through gdb again. thanks for going through all that, but it seems there's something really basic that is causing gimp to complain, like maybe missing files it can't find while in gimp_init .. (although why it segfaults and not return a sensible error message, i don't know)

ok .. i remember you were on irc telling me that it was working with less optimisations? right?
Right. The -Os seems to be the culprit, but I have to say that it was not a problem in any previous version of the gimp, and possibly wont be in the future as well. If you are going to filter this flag out then perhaps add a note that it should be tried out in later versions and perhaps not filtered?
i just upgraded to 1.2.5 and had same problem with -Os compiling with -O3 works as does -O1 didnt try -O2 cause it usally always works CFLAGS="-march=athlon-xp -Os -pipe" is what i usally run has upstream been told of this bug or do they know of it? upstream being gimp or gcc but i have a feeling this is prob gcc's problem anyhow i think replace-flags is in order for the ebuilds for the time being
well, i've put in a replace-flags as a temporary measure.
