Tom and I were looking at this the other day.  The uninitialized  
variable shouldn't matter if it's only used in a sizeof expression.   
The argument to sizeof isn't evaluated (except in the case of C99  
variable-length arrays); only its type is needed.  (Though it is  
probably tidier to use something like sizeof(array[0]) and drop the  
variable reference altogether.)

The memset bug would probably explain the problem, though...
