I see, but the message "Eager macro-expansion failure" doesn't sound like a warning to me. Maybe use the word "warning" somewhere to avoid confusion. > Hence debug-on-error doesn't cause you to get > a backtrace. You'd need to use debug-on-signal for that. The message contains no line number or any other hint where the source of the problem is; debug-on-error is no help either. Maybe it would be better to get rid of the message entirely. Helmut
