Avalon bus addressing wrong

Any idea why in my C code I poll address 0x8000 but actually see 0x0c00 (divide by 2) on Avalon address signals utilizing SignalTap? I would expect to see 0x2000 (divide by 4).

Let me back up....

Have you ever seen where one runs in debug mode & when C code is downloaded the debugger does not stop at MAIN ()?

Normally debugger stops at MAIN() , then user click RUN.

I believe this is the root of my problem.
