Fwd: V8 typeof(Function(str)) is undefined

[victoria yang]

Hi,

  Recently I encountered an issue in V8. 

Issue: 

typeof(Function(str)) is undefined

Env:

Step1: In One Isolate, I create Context A (Run Common JS bundle ) and Context B(Run Business JS Bundle), and set Same SecurityToken.

Step2:  

In ContextA  had JS code Below :

 testFunction(){

  let tmpFunc = Function("(function test(\n) {\nreturn 7;\n})\n");

  console.log(typeof tmpFunc);

}

on ContextA, run testFunction(), console result is 'function'

Step3:

In ContextB, call testFunction in ContextA

console result is 'undefined',

and run tmpFunc(), report Exception ' is not a function'

And For Object.create() 、Object.is() and so on shows OK. Only StringToFunction shows error.

Do you know Why it causes such an issue? Any Advice ?

Pls,help. 

Thank you for your time and I look forward to your reply.

I see you cross-posted this question to the v8-dev mailing list, which probably is a better venue for asking this question. Blink refers to the HTML engine in Chromium, and is not directly related to JavaScript execution.
