I've run the bisection twice, and verified that reverting this on HEAD fixes the problem. I've uploaded my .config to pastebin at http://pastebin.com/kVcr9H65 Even this simple program: main(){puts("HELLO");} compiled with: gcc -m32 test.c Will crash with a segfault. Stracing shows that it's failing to allocate memory. Pat Erley
