g++ 13.0.0 20221009 snapshot (g:e95e91eccd022a4a3a86da2749809fbad9afd20e) ICEs
when compiling the following testcase, reduced from
clang/testsuite/SemaCXX/cxx2a-consteval.cpp from the clang 15.0.1 test suite,
w/ -std=c++20 -O1:
namespace std {
template <typename T>
struct remove_reference {
using type = T;
};
template <typename T>
constexpr typename std::remove_reference<T>::type &&
move (T &&t) noexcept
{
return static_cast<typename std::remove_reference<T>::type &&> (t);
}
}
consteval int
f_eval ()
{
return 0;
}
struct Copy {
int (*ptr) ();
constexpr Copy (int (*p) () = nullptr) : ptr (p)
{
}
};
Copy *
test ()
{
return new Copy (std::move (Copy (&f_eval)));
}
