"Heap exhausted" means that the underlying Lisp implementation has run
out of memory trying to accomplish some operation. In this case, it may
be trying to construct extremely large integers (just guessing). 

Different Lisp implementations manage memory differently. My experience
is that GCL runs into out-of-memory errors more often than other
implementations. Unfortunately the Windows installers are built with
GCL so that is the usual implementation. What Lisp implementation is
your Mac using? build_info(); tells that.

By the way, can you give an example that provokes the error so
we can try it?
