In a lazy-catch handler, you can use (make-stack #t your-handler) to
create a stack object, and then inspect its frames to see where you
think the error might be.  When you find the evaluation frame in
question, you can use frame-source to get the list expression, and
then use source-properties to get the filename, line, and column where
that list came from.  See the Debugging node in the manual for more.
