Idea #1: figure out which Lisp function is being called by funcall (by
looking at the first argument of funcall), then use debug-on-entry to
stop when that function is called.

Idea #2: decrease the values of max-specpdl-size and
max-lisp-eval-depth to cause an error in the Lisp interpreter before
the C stack is overflown.

Done.
