Silence bogus MSVC warning about variable not used
The compiler is wrong: the variable was used in the previous line.
However, the line had no effect for a type T that has a trivial
destructor, so the optimizer must have discarded the line and the
reference to the variable before the checker for used variables.
qsharedpointer_impl.h(247) : warning C4189: 'that' : local variable is initialized but not referenced
