"Kill Monsters" command broken with my mod

As the title says, I have an issue with the "kill" command and my mod (which I will send to the developers).
The only error message I am getting is:
Code: Select all
Execution could not continue.
Ambiguous operand size: mov [r12+32], 0
Only 64-bit of GZDoom is affected while 32-bit works fine.
This build (gzdoom-x64-g3.7pre-302-g927d33306) and previous ones are working fine on both 64 and 32-bits
From this build onward (gzdoom-x64-g3.7pre-733-g101ebe173) it only works on 32-bit while 64-bit gives me the given error message. It doesn't matter if I try to kill specific monster types or just "monsters".

I thought I did, must have done something wrong the first time. This time it was sent correctly.

Here is a minimal sample. It will trigger a failure of
this assertion first, and then, summoning A will lead to this error on JIT code generation.
Code: Select all
version "2.4"
struct S
{
void Func()
{
}
}
class A : Actor
{
override void BeginPlay()
{
S s;
s.Func();
}
}
EDIT: To workaround this engine bug in the mod, it should be enough to make
ParticleSpawner.SpawnParticles() function
static and avoid creation of
ParticleSpawner instances (which is the right thing to do anyway).

I actually compiled a debug build myself before reporting and saw the same assertion failure. Since it was during startup however I thought it was unrelated and that I compiled something wrongly...
Anyhow, I fixed it in my mod, thanks for the clarification.

Is this caused by the zero-length struct?

Yes, because of RegType in VMFunctionBuilder::FramePointer is REGT_NIL to be precise.
