I've created an issue on Github, but seems no one has responded yet:
https://github.com/ZDoom/gzdoom/issues/2724
A clear and concise description of what the bug is.
GZDoom crashes with these two mods in particular: Alice: Toys of Madness v1.0.1 and mercilessmonsv0.7 .
In fact, any mod that replaces monsters combined with Alice will do the trick, I got crashes even with this
it is related somehow to big enemy hordes and dealing damage to them (and taking damage as well). It building up throughout play time and in some point can result in crash, like some sort of counter overflow. If you a killing enemies fast enough it might be just fine.
There are other mods in crash report, but they seems make no difference - I tried to disable them one by one, leaving only three mentioned above, and the game still crashes.
For a mod manager I've used DoomLauncher:

GPU drivers has been updated to the latest version.
Steps to reproduce the behaviour.
Explain how to reproduce
load mods in order: mercilessmons and Alice:ToM (tested: these two is enough to get crashed)
play around 6-40 minutes using Alice:ToM slot 5 weapon and then switch to slot 4/slot 7 on a big slaughtermaps with hordes of enemies. I don't know if quicksaving\quickloading is necessary to get this crash reproduced.
It should freeze with "not responding" in task manager, and if you are very lucky you'll get a crash with a C0000005 error report
