Two possibilities.
a) Something inbetween is changing it. I guess you would have to single step 
and the machine code level.
b) The debugger is not showing the corruption until to late.

This is starting to look like a compiler bug. Which compiler are you using?
Do you have a small test case? If so maybe you can send it to see if the 
problem is reproducable.
