I'm not sure what FreeBSD version you're using

-current, and I update just about every day. I tried upgrading -current 
with a clean /usr/obj today (r209614) and a totally stripped down 
everything (make.conf, loader.conf, etc.) to get as stock as possible, 
then I recompiled gcc 4.5.1 again, still no joy.

but I have
__stack_chk_fail_local alias in libc.
