Bug ID: 115280
Summary: Concept can access private alias in a classs
Product: gcc
Version: 14.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: fchelnokov at gmail dot com
Target Milestone: ---
This program
```
#include <concepts>
class A {
using X = int;
};
template<typename T>
concept C = requires(T t) {
{ t } -> std::convertible_to<A::X>;
};
static_assert(C<int>);
```
is invalid and rejected by Clang with the error:
> error: 'X' is a private member of 'A'
But GCC accepts the program just fine, which looks wrong, online demo:
