            Bug ID: 108116
           Summary: internal compiler error: in check_noexcept_r, at
                    cp/except.cc:1074
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED

When compiling the code

#include <initializer_list>
struct c {
  c(int);
  ~c();
};
struct d {
  d(std::initializer_list<c>);
};
struct e {
  d f{0};
};
template <typename> void h() {
  e{};
}

GCC 12 fails with an internal compiler error.  This happens with GCC 12.1,
12.2, and when built off of the recent git commit
f17ddf2c484427e6ddfd994b62fefcdac27ac02f.  It does not happen with GCC 11.3=
 or
before.  The full error details and preprocessed source are in the attachme=
