But it was the patch available [here](https://github.com/bytecodealliance/wasm-micro-runtime/blob/main/build-scripts/lldb_wasm.patch) is part of WAMR, maybe this patch is different and will make it work. I tried using this patch without success.

Just giving the info here because I'm not sure this patch is supposed to be straightaway compatible with WAMR.

Hi @mh4ck-Thales this is caused by https://github.com/llvm/llvm-project/pull/77949#discussion_r1463458728, currently we need to modify it manually. 

And since this PR is not merged, you need to use the [wasm_debug_2024] branch in my forked WAMR repo for testing: https://github.com/xujuntwt95329/wasm-micro-runtime/tree/wasm_debug_2024
