[Mono] Regression: amd64 AOT: condition `class1 != ARG_CLASS_NO_CLASS' not met

[Perksey]

Description

Unchanged code from .NET 6/7 to .NET 8 no longer compiles against MonoAOT.

Reproduction Steps

1. Use the following .NET 5 artefact: Silk.NET.SDL.dll.changetheextension.txt (or you can attempt to use the latest Silk.NET.SDL NuGet artefact)
2. Attempt to compile using Mono on amd64
3. Observe the assertion fail

Expected behavior

Compiles as it does with .NET 6/7 Mono.

Actual behavior

Does not compile.

Regression?

Yes, these applications compiled on .NET 7

Known Workarounds

No known workarounds.

Configuration

Running on Windows Server 2022 using workload 34.0.0-preview.6.359. Attempting to compile for amd64. It is specific to that configuration as no other configurations failed. CI job: https://github.com/dotnet/Silk.NET/actions/runs/5933030128/job/16087847725?pr=1591

Other information

Perhaps it is indeed some undefined behaviour exerted by our bindings, but without knowing which specific function is exercising that undefined behaviour and causing Mono to crash, I don't know what I can do to work around this.

Note: I don't necessarily think this is specific to Android (it's in the very common mini-amd64.c file), but it's the Android amd64 build that's triggering it...

[fanyang-mono]

I was able to reproduce this issue on amd64 desktop. Removing the android label.
