Correct me if I'm wrong, but how does this theory work:

Assumption: long is twice as many bits as int and big-endian byte order,
both of which should be valid here.

Pretend we have a "long" value of 16. That would get onto the stack as
the following string of bytes: 00, 00, 00, 10.

Now printf() is looking for an integer so it only grabs 16 bits from the
stack which gets the bytes: 00 00

Magically, our "long" value turns into a 0.

The theory is that the format string being used is only cuing printf()
to look for an int value but a long int is on the stack.

I'm not overly familiar with the microware C compiler and the C library
involved but usually "%ld" is used for long ints rather than "%D", is it
not?
