Strange behavior of v8::Private

[Danny Dorfman]

Hello there,

I am trying to use the SetPrivate()/GetPrivate() pair of v8's Object, and I'm having trouble preparing the "key" part.

According to documentation, it should be of type Local<Private>, and there are two API functions that can possibly create it.

At first I tried using Local<Private>New(). Setting the value works, but getting the value will always yield v8::Undefined.

Then I tried using Local<Private>ForApi(). Now setting and getting works just fine, but there's a limitation:

if the key is created from a string that is all digits, the executable SEGFAULTs.

Am I doing it wrong? (My v8 engine is 4.9)

Regards,

Danny
