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
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]

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
}
