That's most likely a hardware problem.
(In reply to comment #3) I doubt if it is. I just recompiled the code outside the gentoo chroot jail using "standard" CFLAGS and CXXFLAGS, it did not crash at all. In fact, I recompiled the stock GCC 4.3.4 from ftp.gnu.org using '-mcore2' flags, and the compiler crashed again.

No idea how to reproduce or fix this :(
hi buddies! it is my first time posting here, and also is my first time reporting a bug, so I hope my post will be useful :) I can reproduce this bug even with a different gcc version. At first, I thought the problem was the computer but... I am trying to change the chost variable from i486-pc-linux-gnu to i586-pc-linux-gnu in my ancient PentiumMMX 200Mhz. I've got heaps 'segmentation fault' while compiling the kernel after a fresh installation, and also while compiling binutils, gcc and glibc for chost issues. But after compiling glibc (with a lot of problems, seg faults, etc), EVERYTHING is working fine now. At the moment my Pentium is making emerge -e system, without problems... So I think the problem could be something related to glibc, cause it is very strange that I spent like 5 days just for compiling gcc and glibc, and now, in half day the computer have finished half of the emerge -e system. Isn't it? thanks (and sorry for my English... I tried my best :D) erFelipe
