Confusing error message from WebAssembly + JS

[jelmervdl]

This happens because assert() is defined by bergamot-translation-worker.js, the Emscripten runtime code:

function assert(condition, text) {
 if (!condition) {
  abort(text);
 }
}

// ...

function abort(what) {
 what = "Aborted(" + what + ")";
 err(what);
 ABORT = true;
 EXITSTATUS = 1;
 what += ". Build with -s ASSERTIONS=1 for more info.";
 var e = new WebAssembly.RuntimeError(what);
 throw e;
}

You could replace assert() with console.assert() which is the more common API for it in Javascript. Downside: console.assert just prints a message but does not stop the program from continuing. So it isn't really equivalent.
