This is not safe to do. What you are doing is passing a scope-allocated 
variable to a function, and then examining the variable after the scope 
has exited (and essentially deallocated the variable).

The reason it "changes" is because your dangling pointer to that data is 
now pointing at the newly allocated variable in the new loop scope.

I would expect this code to behave strangely, and possibly crash.

If you want a variable to exist beyond it's declared scope, you must 
allocate on the heap as Alex said.
