Details

Lucet runtime has a custom signal handler to handle WASM errors... This is (I believe) an optional component as its primary role is to provide a cleaner dump when wasm code crashes... However, its inclusion in the runtime can interfere with Firefox's signal handler when executing wasm sandboxed library code... Need to investigate the right approach between

  • include both handlers in some sort of nested way
  • only use the Firefox handler
  • Combine bodies of both handlers into the Firefox handler

We do not enable lucets signal handler in RLBox, so this is not an issue.
