The guys who first raised it on bugzilla had the same hunch. The
problem is: where do I start? I can't debug in __do_global_dtors_aux()
as there is no debugging info. Do I have to build libgcc.a with
debugging (or whatever it is that supplied __do_global_dtors_aux())?

Thanks, though in my case I am using Sun as & ld (unless gcc comes with
a binutils ld and is quietly using it).
