Actually, by default, AIX only dumps the stack segment, which means
that the average core file is 20K or so.  The program's text segment
isn't dumped, and neither is the data segment.  This results in a
small, quick dump that has enough information to be able to do a
'where' in dbx after the fact (although general variable dumping
after the fact isn't possible).  IBM's theory is that 95% of the
time, you just want 'where', and if you need more information than
that, it's time to run the program under dbx control so you can
debug interactively.
