I'm not sure what you mean by 'in the last few days'.  There was some 
discussion on the list about exit being called from an atexit function:

In fact, I can verify that 971114 still fails in the same way as previous 
builds.  A simple hello world prgram dumps core after main finishes 
running;  __do_global_dtors gets called twice.

Looking at Robert Lipe's message, I wonder if I should undefine HAVE_ATEXIT 
from a header file somewhere.

Thanks,
