Add a check for a NULL return from a malloc/realloc call.  Run the progam, and
when it dies, go back and look at how much memory you were trying to
allocate.  I often find I forget to initialize variable on Solaris and
whatever value happens to be in it gets used.

BTW, one of the best debuggers on Solaris is "ups."  It is by far the most
useful debugger I've ever used.  It is free and can be found at
