I'm using Qt 5.8.0 MinGW 32 bit from Qt Creator 4.2.1 on an HP desktop with a Intel Xeon CPU in Windows & Professional 64 bit service pack1 OS.
I keep getting a segmentation fault when running this code (in debug) at the point where I attempt to load an image using QPixmap.

I believe my pointers are initialized correctly nor can I notice any uninitialized pointers or out of bound arrays (unless I'm looking right at it and can't see it). In the following code, some of the documented out lines are various ways I've attempted to load the image.

I'd appreciate anyone who can spot why I'm getting a SIGSEV error on this and thank you in advance.
