when the CFLAG of -fomit-leaf-frame pointer is used in conjuction with GCC 4.0.1, an emerge of python 2.4.1-r1 will fail with a segfault. Reproducible: Always Steps to Reproduce: 1.

try gcc-4.0.2
some problem here he difference is that i have gcc-4.0.2
the same problem occurs with the new python 2.4.2 ebuild. i havent tested gcc 4.0.2 yet though.
(In reply to comment #2) > some problem here he difference is that i have gcc-4.0.2 And your CFLAGS? Could you try with a sane set of CFLAGS, something like "-O2 -march=pentium3 -fomit-frame-pointer -pipe". I personally have not had the problems described here yet, and I haven't heard from others that I know to be running gcc-4 describing this problem.
I get the same with python 2.4.2. Mabey its's because I use glibc-2.3.5-r3. Mabey I should use glibc-2.3.5.20050421 or newer my flags: CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
get back to us
