Need help with memory leak and stepping thru a method

[joofung@iss.nus.sg (Wong Joo Fung)]

Hi folks:

I am encountering a strange problem where each invocation of my MCL program
causes me to loose about 25K of the Mac heap (I did a gc and room before and
after invocating the program).  And after several rounds of coding/testing,
MCL bombs when it runs out of Mac heap space.  (The Lisp heap is OK though).
I did traced my CLOS methods and the ones that deallocated Mac structures
were apparently invoked.  Would you have other ideas that I can try?

Also, could anyone tell me how the trace statement can be used to step thru'
a CLOS method.  That is, I used

   (trace ((:method dispose (container))))

to trace the dispose method within my container class, but I couldn't get it
to step through the code in the method.

Any help would be much appreciated.

Thanks,
JooFung Wong
