   I am not sure if this is a *bug*, but it sure behaves strangely...  If you
   compile the following program on a Sparcstation or Sun 4, you will get 

   foo: a is -14249818

   (or something similar).  If you compile it on practically anything else,
   (ie, DECstation, Sun 3, Sequent, Vax) you get 

   foo: a is 22

This is because unions are passed by reference (pointer).  The program is,
of course, to blame.  try linting it, then shoot the authors of that 170k
line program.
