null function or function signature mismatch

[davidsiaw]

Thank you for your awesome work getting Ruby to work in the browser. I had a play around and found that after running it for a while it crashes with an issue:

Tried to report internal Ruby VM state but failed:  RuntimeError: null function or function signature mismatch

You can easily reproduce this bug by using the following file:

https://github.com/davidsiaw/rubywasm-crash/blob/master/public/index.html

And wait for anywhere between 1 minute to 10 minutes.

I attempted to workaround the issue but it seems like once it hits this error it cannot recover, even with a try catch around the step function in JS.

Could you try version 2.6.1-2024-06-14-b? It includes a fix around GC issue

I have also seen the similar error message with custom ruby build with rbwasm.
Would you mind giving me the instructions for using the ruby you mentioned?
I guess it could be done by rbwasm build --ruby-version. However, I could not complete it.

@tani You just need to upgrade ruby_wasm and js gem in your Gemfile, and corresponding npm packages. Just published 2.6.2, so you can use it now.

Great. I now confirm that my issue is solved.
Asciidoctor-wasm works expectedly. Thanks!
