Finalize fails with json.decoder.JSONDecodeError: Expecting ',' delimiter

[KeyboardDanni]

I can't seem to compile my Rust-based application on the latest emscripten (tried 2.0.23 and 2.0.22). Seems like wasm-emscripten-finalize is spitting out invalid JSON:

json.decoder.JSONDecodeError: Expecting ',' delimiter: line 30 column 22 (char 9178)

The bad line appears to be here, where unescaped quote marks are being inserted:

"__invoke_void_%"std::vec::Vec<std::boxed::Box<dynkeeshond::scene::Component>>"*",

I'm assuming that wasm-emscripten-finalize would just need to look for quote marks in these names and replace them with \"? Or should the quote marks not be there at all?

Full error log attached.

Did some more testing and it seems that emscripten 2.0.6 is the last working version.

This is with rustc 1.51.0 stable if it's relevant.

This is an issue the version of clang/llvm being too old.

@tlively what is the recommended path for rustc users here?

After upgrading my version of rustc, it seems like this is resolved. I can't switch to latest emscripten yet due to #14313 but seems like 2.0.13 works.
