Crash after reloading dll sometimes
I have a game with hot reloading and sometimes after recompile and the game reloads dll, raddebuger will crash. This isn't problem with compile errors because the dll still exists and rerunning works. Most of the time the reload works fine though. This isn't a critical issue for me just thought you might want to see the exception window info.

Just tried out on 0.9.14 but can't reproduce because it was quite infrequent so I will continue using it and let you know if it happens again. Did you already try to fix something like this on later versions?
It happened again on 0.9.14 this time. Was after a hot reload recompile again.

Sorry for the delay on this. Many parts of the evaluation system have been overhauled in 0.9.16, including the places where this crash occurred. Would you be able to give it a try on 0.9.16 now? I am not able to easily reproduce it with the hotloading tests I've got, unfortunately.
Just tried to hot reload on 0.9.16 but no crash happened. If it still crashes I probably won't find it as quickly as last time because I finished working on the game. The crash happened quite a few times on 0.9.14 and even on 0.9.15 but I never realized anything reproducible about it.
Whenever the crash happened, after reopening there would be a new invalid target that I have to delete. Also if it could be anything about the way the hot reloading is done then everything is in this file: https://github.com/toodemhard/multiplayer_2/blob/main/src/platform/app.c.
I think this hotloading setup should work fine. I think this bug has likely disappeared after the recent evaluation/evaluation-visualization/callstack system passes, since this was a crash in building type strings for function types in a call stack. Please let me know if you see it again.
Yeah I think it was very likely fixed in the overhaul because I still have no crashes since 0.9.16.
