            Bug ID: 51967
           Summary: gsl::Owner seems not to work on custom class
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement

Looking at https://reviews.llvm.org/D64448 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?

https://godbolt.org/z/571sYxad3

#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
}
