--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Probably the same issue:
struct A {
void operator delete(void*) = delete;
void operator delete[](void*) = delete;
};
using type1 = decltype(delete (A*)0);
using type2 = decltype(delete[] (A*)0);
Neither of these invalid delete expressions gives an error.
Clang says:
e.cc:6:24: error: attempt to use a deleted function
using type1 = decltype(delete (A*)0);
^
e.cc:2:8: note: 'operator delete' has been explicitly marked deleted here
void operator delete(void*) = delete;

e.cc:7:24: error: attempt to use a deleted function
using type2 = decltype(delete[] (A*)0);
^
e.cc:3:8: note: 'operator delete[]' has been explicitly marked deleted here
void operator delete[](void*) = delete;
