You have to deallocate only if the ownership still with the
same object. This is not the case when the object is moved.

Take this code
string str;
int main ()
{
string str( "hello" );
::str = move( str );
}
With clang-cl (the MSVC-flavour of clang) the whole string-creation
and destruction is opmized away and the compiler directly checks if
::str contains any externally allocated and if not it makes a short
-string-optimized "copy" to ::str. That's nine instructions for the
whole string copy with clang-cl 17.0.3; no external call.
