hi there,

i'm having similar issues with libc. while doing buildworld i got this segfault:

Stop in /usr/src.

i'm not sure if the gdb command i used is correct, since i found two versions of `cc` in /usr/obj:

find ./ -type f -name cc ./usr/src/tmp/usr/bin/cc ./usr/src/tmp/usr/src/gnu/usr.bin/cc/cc/cc

i've used gdb /usr/obj/usr/src/tmp/usr/bin/cc /usr/obj/usr/src/gnu/lib/libssp/libssp_nonshared/cc.core to get a backtrace. hope i picked the right version:
