It's likely that the code involved is something like:

   foo = malloc (N);
   if (!foo)
   {
        printf ("Out of memory\n");
        exit(1);
   }

So as a generic debugging tip, run the program through 'dbx' (make
sure you're in single-process mode) and set a breakpoint on exit().
When you reach the breakpoint, type 'where' and you'll be able to see
the function leading to that message. This may provide some hints..
