I tried to run rune inside a WebWorker today and for debug builds I get a stack overflow. For production builds this problem is not showing up... For minimal rune code (just variable in and out) this problem is also not appearing at debug builds.

Here is the console output for more details

Is there anything which can be done? How is the status about a 0.14.0 release? Could this fix it?

Nothing that can be done without a significant compiler rewrite. For now it recurses into expressions and a particularly sized stack will be required depending on which script is being compiled.

Ok, thanks for the fast feedback. I will try to optimize the generated .wasm with warm-pack better for dev-builds.
