No worries.

Good news!

I would really like to have some more information about these leaks.
Note that if there are some types that require a %destructor, but
you don't provide one, then there is nothing that Bison can do to
release them.

The more I think about it, the more I believe that I took the wrong
path, and exception safety should be addressed at the yyparse level:
put the whole function into a try/catch block.  That way, we are
also protected from errors in %printer, %destructor, %initial-action,
yyerror, and maybe other places I didn't think about.  I will provide
another patch in the near future.

Thanks!
