It doesn't work for me. The error reported with JS_ReportError is passed 
to the error reporter I have configured with JS_SetErrorReporter, but I 
don't get a catchable exception my script just exits.

I tried printing the value returned by JS_IsExceptionPending after 
calling JS_ReportError, like this:

JS_ReportError(ctx, "Invalid argument - not an int");
cerr << "after JS_ReportError: " << JS_IsExceptionPending(ctx) << endl;

... and it tells me that an exception is not pending.

Under what conditions will JS_ReportError not raise an exception?


Thanks for helping with all my rookie questions.
