I modified the original test to take an argument, which is the position in
the file containing the independent stored object at which to put a null
(%U character).  Depending on what argument I pass (this is Solaris SPARC
32-bit) on 6.4.76313, I get different failure results.  It seems that from
a programmers point of view, I should always get "retrieve exception".  
Otherwise I have to catch all exceptions when retrieving.  Certainly, the
"floating point exception" (last case below) seems to be a bug.

With argument of 0:

Retrieve exception 
(Program caught retrieve exception, rescued it and printed this.  Seems like
 a correct result).

With argument of 4:
