--- Comment #12 from Johel Ernesto Guerrero Pe=C3=B1a <johelegp at gmail do=
t com> ---
The workaround of Comment 5 stopped working for my actual use-case some time
ago. Now I do this:

```C++
export constexpr void expects(bool truth) noexcept {
  if (not truth) std::terminate();
}

// Workarounds GCC bug 99377.
export constexpr auto expects2 =3D expects;
```

FWIW, I've attached the debug and release `.gcm` and `.o` (without the
workaround above), which might hint as to what's (not) happening.=
