AFAICT the problem is that promote_debug_loc crashes when the loc list for a VALUE is temporarily cleared within alias.c to avoid infinite recursion. Getting it to return if passed a NULL pointer seems to be the correct fix. AFAICT we won't run into this except within var-tracking. --- Comment #4 from Alexandre Oliva <aoliva at gcc dot gnu.org> 2012-06-18 10:32:01 UTC --- Mine.
