Crashes the repl

[dandv]

I'm trying to use this module to work around a limitation in WebStorm: it doesn't allow top-level await.

aawait.mjs

import aawait from 'deasync-promise';

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}
debugger;
aawait(sleep(1000));

Note how the repl> prompt turns into debug>.

In WebStorm, this manifests through a SIGSEV:
