yep, +1 on Alex's revert... my appologies.

Of course the passed pointer to the callstack is only a "carbon-copy", so we set 
it to NULL in the scope of that current stack, but have again the "orginal 
pointer" when we return from subsequent stack call and hence this way there is 
no chance to set the "orginal pointer" to NULL.

Even the macro Andreas suggested doesn't help. Since we would need to take care 
to pass the orginal pointer all the way to the callstack. Which seems not that 
easy, or even not possible at all.
