Branch: master Commit: cbb9b101d18e4c1682ca39a52a201d8e4241ea17 POC is:

function attach(f) {
  (function (r) {
    WScript.Attach(r);
  })(f);
}

async function mainTest(notAttachCall) {
    if (notAttachCall) {
        for (let i = 0; i < 1; []) {
            await attach(mainTest);
        }
    } else {
        var i = 10;/**bp:locals()**/
    }
}
mainTest(true);
WScript.Echo("PASSED");

In release build, ./build.sh --sanitize=address --static -j I get:

Thank you for the report. This fails an assert without sanitizer.
