I did have them turned on, but I missed the message. The warning was near the top of a project with 22 source code files. I simply didn't see it.

Everyone makes mistakes. At least I admitted it and posted it here in an effort to help others from making the same mistake.

This what happens if you turn off warnings. Turn them all on. It would have warned that you were implicitly casting a pointer to a different type.

All:

I just made a really dumb mistake which proved hard to debug. I was trying to call a function named ReadSelectButtonPress(), which returns an integer value using the call:

?? val = ReadSelectButtonPress;

It was not behaving as expected so I placed some scaffolding print statements in the function, recompiled, ran the code but never saw the debug prints. Clean compile, so errors.

It's one of those flat-forehead mistakes. I left the function's parentheses off the calling statement. I'm not positive, but looking at the number I was seeing for val, I think the code assigns the lvalue for the function into val. If it were really behaving like a pointer to function, it would have executed the function code.

I'd be embarrassed to tell you how long I spent chasing this bug...
