c/5925: execs crash in shared lib destructor = do_global_dtors_aux

[Daniel van Vugt]

With respect to GCC bug 5925;

http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=5925

I seem to be getting the same problem with gcc 2.95.2 on SCO OpenServer 
5.0.6. It only occurs with our proprietary code and I can't seem to 
replicate the problem using hello.tar.gz. Stepping through in GDB, the 
segfault always occurs somewhere in the __do_global_dtors_aux of one of 
our shared libraries.
