<pre>Looking at <a href="https://reviews.llvm.org/D64448">https://reviews.llvm.org/D64448</a> I was expecting a warning on both
lines inside of fun(), but I only get the warning with unique_ptr. Is this a
bug or am I not understanding who this should be used?

#include <memory>
template <typename T>
struct [[gsl::Owner]] my_unique_ptr
{
T* m_p;
T* get() const { return m_p; };
};
std::unique_ptr<int> get_unique_ptr();
my_unique_ptr<int> get_my_unique_ptr();
void fun()
{
int* p1 = get_my_unique_ptr().get(); // no -Wdangling-gsl
int* p2 = get_unique_ptr().get(); // -Wdangling-gsl
}</pre>
