The createPBufferFromClientBuffer is causing a fatal exception.

I'm using node v0.10.22

The error can be obtained using the openvg-canvas example shadows.js

The error occurs in the call to createPBufferFromClientBuffer. From my investigation, the openvg call returns a scalar value as an EGLSurface (i.e. not a pointer). i.e., it returns '2' and so it is some sort of handle. Then, when this gets wrapped by External::New(surface), it fails before returning to javascript.

There is also an error that gets output to the primary console:-

 Unhandled prefetch abort: breakpoint debug exception (0x002) at 0x004d1b4c 

Since there are screenshots of this sample working, maybe it is related to the version of node.js?
