Works completely fine on my amd64 dual core opteron, with gcc 3.4.6-r1 and same glibc, ironically (this box has emacs-21.4-r3). I seem to recall another instance of it segfaulting with emacs
Is it just cscope? Or do emacs extensions (eg. from app-emacs/) exhibit the same behaviour when compiled in general. What is the result of trying to byte compile an emacs extension outside of portage (ie. manually)
Also, have you tried with CFLAGS="-march=i686 -O2 -pipe"?

(In reply to comment #4) > Also, have you tried with CFLAGS="-march=i686 -O2 -pipe"? I was having this problem with Subversion -- emacs would segfault while attempting to byte-compile duing the subversion emerge. Doing a CFLAGS="-O2 -pipe" emerge -av emacs subversion allowed the subversion emerge to complete. Previous CFLAGS for the emacs build were CFLAGS="-march=athlon-xp -mtune=athlon-xp -O3 -fomit-frame-pointer -ftracer -fprefetch-loop-arrays -pipe"
*** Bug 143410 has been marked as a duplicate of this bug. ***
I think this is a dup of 136987. The problem is not with the port you're compiling (eg. subversion, xcscope etc.) but with how emacs was built in the first place. *** This bug has been marked as a duplicate of 136987 ***
