            Bug ID: 40437
           Summary: requires clause on a destructor produces invalid
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++2a
          Assignee: unassignedclangbugs at nondot.org
          Reporter: antoshkka at gmail.com

Consider the example:

#include <type_traits>

template<typename T>
struct Y {
    ~Y() requires(std::is_trivially_destructible_v<T>) = default;
    ~Y() requires(!std::is_trivially_destructible_v<T>) {}

struct B { ~B(); };


The static_assert passes, however Y should have non trivial destructor.
