Summary

0000436: Peculiar event bug with certain simultaneous events

Description

Sorry to submit so many bugs all at once. This is apparently one of those corner cases that slips through because it is so unusual.

I'm using a custom event to fake local variables. The custom event is configured to fire whenever the value of _stack changes. When _stack increases, I save the local variables, and when _stack decreases, I restore their previous values.

Everything works fine when I invoke sections using gosub(). My custom event is triggered prior to the first line of the subroutine, and again after the last line of the subroutine.

When a subroutine is registered as an event handler and triggered by an event, I find that my custom event occurs AFTER the first line of the subroutine. This is the only problem; the end of the routine works just like it does when invoked by gosub().

Attached is a robot that demonstrates this behavior.

If it were me, I would probably decide this is not worth fixing.

Additional Information

Print output from the robot:

   1: executing auto_stack (pushing)
   1: about to call gosub_section
