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

find ./ -type f -name cc
=2E/usr/src/tmp/usr/bin/cc
=2E/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=
=2E
hope i picked the right version:
