thanks!

I'm using a native compiler and I'm not sure how easy it will be to
reproduce the
failure, as it happens during stage3 build using the compier from stage2
when
on "regclass.c" source. regclass.c passes the compilation when cc1 from
stage1 is used.

I've tried to get a backtrace using gdb, but I'm getting the following
error
from gdb:
(gdb) b main
