[Webkit-unassigned] [Bug 263965] Concurrency bug in WebAssembly LLInt compilation

--- Comment #3 from Ian Grunert <ian.grunert at gmail.com> ---
I spent some time looking at this today. On a release build, I was able to repro this even with a single wasm compiler thread.

With the logging enabled for WasmEntryPlan and WasmWorklist, on a single thread it was able to complete wasm compilation - crashed afterwards with the same stack trace as before.

Couldn't repro on Gnome Web running under WSL. No problems running JetStream2, I wonder if it's something to do with the number of functions involved (520).
