ZDoom

Looks to be a duplicate of this: https://forum.zdoom.org/viewtopic.php?f=2&t=63596
which perfectly explains what happens. Once that older handler gets collected it'd take the new one away with it as well.

In that case I'm pretty sure it's the garbage collector - one way to make sure this bug kicks in is to kill at least 3 zombies with a single grenade, which spawns a huge buttload of actors and thinkers and whatnot all at once.

And it seems I can't replicate this if I use "+map map15" in the command line, only if I use "+map range" (EDIT: or "-warp 01" with the isolated sample) and then IDCLEV15. Knox reported on Discord that he got this bug when he went from map01 to map02 as well.

If you want to catch its destruction, add a Console.Printf to its OnDestroy method.
The only other way than intentional destruction is that it gets caught by the garbage collector, but even that goes through that method.

1. Warp to Map15.
2. IDDQD.
3. Faff around for a few minutes. (EDIT: you don't even need to do anything, but it is easier to see when the bug kicks in if the logspam isn't just zero.)

Expected: the logspam just keeps going.
Actual: after a while it just stops.

It doesn't seem to be related to anything I'm doing, but it seems I can't replicate it without monsters around.

Is there some way to isolate the moment when an eventhandler is destroyed?
EDIT: And how *is* an eventhandler destroyed, other than by calling "destroy()" (which HD definitely does not do at any point)? Knowing how it might disappear would help a lot to isolate this, I suspect.



EDIT: Isolated example attached. Ran[code]gzdoom -file ~/handlertest -warp 01 -fast -skill 4[/code]IDCLEV15'd and ran around in the courtyard after also summoning about 50 chaingun guys, the logs stopped shortly after.
