Strange behavior in Node debugger (REPL)

[svlapin]

Hello,

first of all, thanks for amazing module!
I pretty enjoy it and everything works awesome until I try to do some things in Node debugger.

Consider the following trivial snippet (test.js):

var Curl = require('node-libcurl').Curl;

var curl = new Curl();

debugger;

Run it in debugger mode:

$ node debug test.js

And after pressing c to continue, get stopped at the breakpoint. Type repl + Enter, get into REPL console.
Type curl and hit Enter, and get the error:

node: ../node_modules/nan/nan_object_wrap.h:33: static T* Nan::ObjectWrap::Unwrap(v8::Local<v8::Object>) [with T = NodeLibcurl::Easy]: Assertion `object->InternalFieldCount() > 0' failed.
program terminated

I guess it happens because debugger tries to obtain some internal structure of the Curl instance.

Also, that does not reproduce if I start in REPL from the very beginning:

$ node

> new (require('node-libcurl').Curl)()
Curl {
  domain: 
   Domain {
     domain: null,
     _events: { error: [Function] },
     _eventsCount: 1,
     _maxListeners: undefined,
     members: [] },
  _events: {},
  _eventsCount: 0,
  _maxListeners: undefined,
  _handle: Easy { onData: [Function: bound ], onHeader: [Function: bound ] },
  _id: 1,
  _chunks: [],
  _headerChunks: [],
  _chunksLength: 0,
  _headerChunksLength: 0,
  _isRunning: false,
  _features: 0,
  onData: null,
  onHeader: null }

Thanks.

Hi, thanks for the report.

From what I can see, this is a bug with node itself, see this issue: nodejs/node-v0.x-archive#9028

Closing this, since it's not something I can fix from here.
