Incorrect handling of boolean values from a native (node-gyp built) module

[dazwin]

I've created a sample node-gyp project that returns boolean true/false values. It works as expected running under node, but when run under electron-prebuilt the values are incorrectly interpreted.

A sample project can be found here: https://bitbucket.org/kwaaioak/electron-test

Here's the substance of what I'm doing...

In C++:
attributes->Set(Nan::New("should_be_true").ToLocalChecked(), Nan::Newv8::Boolean(true));
attributes->Set(Nan::New("should_be_false").ToLocalChecked(), Nan::Newv8::Boolean(false));

When run under node:
should_be_true = (boolean)true
should_be_false = (boolean)false

When run under electron:
should_be_true = (boolean)false
should_be_false = (string)

This doesn't seem like it should be an Electron issue, but starting here anyway.

$ node -v
v6.2.0

$ node-gyp -v
v3.3.1

$ ./node_modules/.bin/electron -v
v1.2.5

The results are the same whether I'm using electron or electron-prebuilt
