Referencing function in another module

[miguel-petersen]

When using intrinsics such as llvm.gla.fTextureSample.v4f32.v2f32, during the validation pass the validator spits out:

Referencing function in another module!

Now, I have declared no other module, and as far as I know no "internal" module is created inside the LunarGLASS project. The error is generated by this (LLVM, Verifier.cpp, 2074):

Assert1(F->getParent() == Mod, "Referencing function in another module!", &I);

And it turns out that the parent (Module pointer) is null for some reason, now I could not find the reason however I added an illegal (Guarenteed to fail at some point) to keep things running for now:

Assert1(F->getParent() == nullptr || F->getParent() == Mod, "Referencing function in another module!", &I);

And the correct glsl (From the glsl backend) is generated, so I assume this will work for now. However I would like to avoid this for future use, any ideas what could cause this?

Thank you for your time.
