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).
