Why does running my mex function cause matlab to shutdown?

For some reason the mexw64 function I have compiled causes matlab to shut down on me. I compiled the mex function in visual c++ 2010, and none of the source code has any sign of the function 'exit()', which i found was a common cause here:

Ideas anyone?
