As far as I remember (couldn't find modern documentation on the matter) 
Valgrind is resitant to this problem. When a block of memory is copied, 
the initialized/uninitialized status is copied along. It only complains 
when an actual operation is performed using uninitialized memory. This 
was developed for the explicit reason of avoiding the problem you describe.
