That means, only allow construction and copy assignment when the type X* is convertible to type T*. This is done using SFINAE and the std::is_convertible type trait, which makes the previous QSHAREDPOINTER_VERIFY_AUTO_CAST obsolete. This patch fixes compilation when a function is overloaded with Q{Shared,Weak}Pointer of different, incompatible types. Previously, this resulted in a compilation error due to an ambiguous overload.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qstrnicmp() has an assertion that the lhs string is not nullptr.
