Wasm32,infinite loop, no stack overflow: how to get stack?

Here's my problem:

  1. I have a piece of Rust/wasm32 code.

  2. It appears to be infinite looping (freezes the browser tab.)

  3. There appears to be no panic, no stack overflow, no stacktrace of any form in the js console log.

  4. This seems to be an infinite loop without increasing the stack size.

My question: is there a way to "force kill" the wasm32 app and get a stack trace out somehow?
