Try breaking out the call path to examine each succeeding value when assigning
a value to display. One thing that jumps out at me: are you running this in
64-bit mode? The size of an int in 64-bit mode is 32 bits but a
CGDirectDisplayID may have 64 significant bits as it's technically a pointer.
I'm not sure how many bits are significant in a CGDirectDisplayID when run in
64-bit mode; at least, if I were Apple, I'd just leave 32 bits significant for
cases like this, but I'd still check that.
