/*
Since the PoC is only triggerable when the "DeferParse" flag enabled and requires a with statement, I think this is simillar to issue 1310 .
PoC:
*/
// Enable the flag using '\n'.repeat(0x1000)
eval(`(function f() {
with ({}) {
(function () {
print(f);
})();
}
}());` + '\n'.repeat(0x1000));
PoC 2:
// ./ch poc.js -ForceDeferParse
(function f() {
with ({}) {
(function () {
print(f);
})();
}
}());
