It's difficult to determine what's going on here, but this line

error: failed to build archive: 'wasm32.o': section too large

Implies that perhaps too much code was being generated (although I'm not sure why that would be the case). Are you compiling with optimisations enabled?

I just use command:wasm-pack build --target bundler

This seems much more likely to be an issue with wasm-pack than chumsky, I'd recommend asking on the relevant GitHub repo instead.

Try building in release and see if the issue persists. In a project that I was working on, I found that the debug build included type information that was larger than some limitation in the wasm parser. When I built in release mode, that type information wasn't included, and so it worked. Its obviously not ideal, but at least its a workaround until a final solution is implemented.
