App wont initialise on device

Hi, I have just tried to recompile my app and for some reason it is now crashing when it tries to initialise OpenGL.

An external call is made to AllocateRenderBufferStorageFromEAGLLayer within the Unity > EAGLContextHelper.mm and it just freezes.
This is the output from XCode:

2015-07-03 13:25:35.660 EWAY[692:70161] -> registered mono modules 0x1014897b0
