In the past there has been talk about older UNIX code which
expected to be able to successfully dereference NULL pointers.  I'm
involved in a port of SysVr1 UNIX and have so far found one such
instance in the source for "cat".  I'm presently hunting for a pointer
problem in the Bourne shell and got to wondering if it could be a
similar situation but masked by much more complicated code.  Does anyone
have a list of, or know of, code in any SysVr1 utility which wants to
dereference NULL? 

Thanks in advance.  Please send mail, I'll summarize if there is interest.
