Most Lisp debuggers will do this with compiled code.  I know of nne which
do this to compiled code without recompilation.

I apologize for the lack of context in my reply - it was late last night
and I have no time this morning as well; Lisp, and in particular CL, does
very well in debugging interpreted code.  However, just as I detest the
need for a -g option in gcc, I always strive to avoid requiring the
user to recompile in order to get debugging info.  In CL, the debug
quality interacts with but is separate from the speed, safety,
compilation-speed, and space qualities.
