Julian Seward sent me a pointer to an app called "valgrind" which
I think may perhaps help here? I have played with it, but I am 
at a loss to interpret its results.

   Valgrind  is  a GPL'd tool to help you find memory-management problems
   in  your programs. When a program is run under Valgrind's supervision,
   all   reads   and   writes   of  memory  are  checked,  and  calls  to
   malloc/new/free/delete  are  intercepted.

Frank will note it's Linux-specific and x86-specific, but I'm sure
he knows other tools for other platforms :) 

If I misunderstand the problems from the thread and the nature of
this valgrind app, my apologies; but it seemed an opportune time
to mention it. 

Since I am staring at the output and wondering which bits are 
relevant, which are normal, which are X, and which are bugs, I
think other people should have a play with it, because they 
might understand it.
