bjorn3 commented on issue #3184:

The debuginfo seems to be missing a DW_AT_comp_dir. Wasmtime expects it to exist: https://github.com/bytecodealliance/wasmtime/blob/d7053ea9c71b4a240c1966bd1bd9424e36a44f28/crates/debug/src/transform/line_program.rs#L671 I think it is valid to omit it though for as long as it is not referenced from the line program (it isn't for this file)
