Oops.  Yes, that is unexpected.  I think your solution is essentially
correct, except that you shouldn't use procedure->memoizing-macro (use
define-macro instead) and that you inject literal procedures into the
expanded code.  This is not good style since the procedures are
created in the compile time environment but used in the run-time
environment.  A compiler might not like this.

This old post might be interesting as well, but the 'tagbody'
implementation in it is not properly tail recursive:
