Subject: [PATCH] Fix GCC 13 warning about freeing the global static

I believe the problem is that QGlobalStatic::operator Type *() may
return a null pointer, in which case the compiler is right that we could
attempt to free the shared_null. Instead use QGlobalStatic::operator*,
which doesn't ever return nullptr.
