"unreachable" WASM instruction executed.

The typical reason is a PHP function missing from the ASYNCIFY_ONLY
list when building PHP.wasm.

You will need to file a new issue in the WordPress Playground repository
and paste this error message there:

https://github.com/WordPress/wordpress-playground/issues/new

If you're a core developer, the typical fix is to:

* Isolate a minimal reproduction of the error
* Add a reproduction of the error to php-asyncify.spec.ts in the WordPress Playground repository
* Run 'npm run fix-asyncify'
* Commit the changes, push to the repo, release updated NPM packages

Below is a list of all the PHP functions found in the stack trace to
help with the minimal reproduction. If they're all already listed in
the Dockerfile, you'll need to trigger this error again with long stack
traces enabled. In node.js, you can do it using the --stack-trace-limit=100
