Description

That warning comes from binaryen here:

https://github.com/WebAssembly/binaryen/blob/44c3c2d4e71686d42b7eff8ab9c554f83a9fe71e/src/wasm/wasm-binary.cpp#L1575

I'm not sure what it does actually as it doesn't seem to actually skip it... but I'm also not sure if it's ok to just remove it.

Research direction

Start with src/wasm/wasm-binary.cpp at line 1575 and read the surrounding binary debug-location handling. Trace why the “skipping debug location info” warning is emitted and whether the location data is actually skipped. Done means the warning’s behavior and intended handling are established, with any change covered by the relevant existing test path.
