Previously, debug_return_bool was the same as debug_return_int

except that it logged true/false for 1/0.  However, this appears
to trigger a bug in some compilers.  To avoid this, debug_return_bool
now uses bool, not int.  Callers that were passing it an int have
been converted to use debug_return_int instead.
