To quote @cfallin from https://github.com/bytecodealliance/wasmtime/issues/4669#issuecomment-1210997950 (which is probably the same issue):

We currently don't have anyone on the project who understands our DWARF-handling code well and has time to work on it; so while this is definitely a bug, it's not likely to have a fast resolution. We do have an intent to have someone eventually focus on this, as priorities allow, so we should keep this issue open. Just wanted to give some context on the current situation...

I believe this is more-or-less a duplicate of https://github.com/bytecodealliance/wasmtime/issues/3999 so I'm going to close this in favor of that. I'd also highlight Chris's quote as well and recommend against enabling -g for now.

Thanks for filing an issue! Please fill out the TODOs below.

Steps to Reproduce

wasmtime run -g starter.wasm (wasm attached)

starter.was.zip

Expected Results

Debug execution should work. Program executes correctly without the -g flag.

Actual Results

# wasmtime run -g starter.wasm
