Note: Where possible, please avoid attaching screen shots of code or console
logs. Instead, please include them as text so that they may be copied /

escape them with three backticks before and after, like this:
It looks like that combination of flags is not allowed: https://github.com/emscripten-core/emscripten/blob/74ada8315172abe32db7b475f52e5e2612dfbc9b/src/library_wasm_worker.js#L22-L24
However, the compiler should not crash so we should fix that.
It would be nice if we can have this feature that allows merging wasm workers with single file just like pthread with single file. @sbc100.
