Another thing you can try is to code your own delay
loop. Just do something in a loop that doesn't get
optimized away (sometimes tricky).  Then if it
works with your delay routine, you know something is
up with the called on.

You might need the help of the:

pragma Volatile(Variable);

in your own delay loop. Otherwise, if you compile with -Os,
you should be ok.
