Re: [v8-users] v8 shell crashes with Fatal error in v8::ToLocalChecked Empty MaybeLocal.

The whole point of a MaybeLocal is that it *may *(or may not) contain a value. Calling .ToLocalChecked() on it is unsafe, unless you happen to know that it can't be empty. shell.cc:416 is doing it wrong. d8.cc:883

Thanks. Any tip in debugging this kind of failures? I don't seem to get a stack even though I'm using debug build both for v8 and my embedding app. On Monday, October 5, 2015 at 1:59:46 PM UTC-7, Jakob Kummerow wrote: > > The whole point of a MaybeLocal is that it *may *(or may not) contain a
