iOS PPSSignature bad access

I have a main video view controller, where I present a modal navigation controller so I can still access the video VC.

From the nav controller's root VC, I then can display a 2nd VC with a PPSSignatureView. However, upon using the PPSSignatureView, I get a EXC_BAD_ACCESS (code = 1, address = 0x0) at memcpy line below:

`// Append vertex to array buffer static inline void addVertex(uint *length, PPSSignaturePoint v) { if ((*length) >= maxLength) { return; } GLvoid *data = glMapBufferOES(GL_ARRAY_BUFFER, GL_WRITE_ONLY_OES); memcpy(data + sizeof(PPSSignaturePoint) * (*length), &v, sizeof(PPSSignaturePoint)); glUnmapBufferOES(GL_ARRAY_BUFFER); (*length)++; }`

The PPSSignatureVC works when I was just testing it alone without any of the nav controller modal stuff going on. Any ideas how I can stop this error? Appreciate any help!
