>Organization:
>Environment:
kernel-2.4.20, glibc-2.3.1, gcc-3.2.1, binutils-2.13, bison-1.875 (all of these compiled with gcc-3.2.1 -march=k6-2 -O2). Amd k6-2, 256MB ram.
>Description:
Bootstrap fails compiling gcc-3.2.2 or any snapshot after 20021125 (it included, I don't know if any between 20021125 and release fails also). I'm sure gcc-3.2.1 doesn't segfault, I build it 3+ times. I also try to reproduce the segfault on a K7-atlonxp with redhat8 but I can't. Segfault usually happens running xgcc at stage1. Once the bootstrap fail, running make bootstrap again will resume the build without the same segfault (another will happen another one in a few compiles). I know that this info won't help to locate the bug but I post here to know if it happens to somebody else. How I can provide usefull info?
>How-To-Repeat:
I can't in any other machine. Maybe with gcc-3.2.1 optimized for k6-2 in a k6-2.
