LLJIT running out of memory when addIRModule is called in WASM

Beginners

I’m trying to run LLJIT in wasm, I compiled it with emscripten. I was able to produce LLVM IR, but as soon as I’m trying to add the ThreadSafeModule, ExitOnErr(llvmJit->addIRModule(std::move(threadSafeModule))); it runs out of memory.

This is completely absurd, that almost 2.8GB are requested, since I’m only running the same module from the example.

Do you guys have any ideas, why this could happen or any ideas how to debug this and find the cause of it?
