--- Comment #4 from Johel Ernesto Guerrero Peña <johelegp at gmail dot com> ---
This is actually Bug 106826.

Simplest: https://godbolt.org/z/oKT4x9r4G.

```C++
template<class> constexpr bool is = false;
template<class T> constexpr bool is<T&> = true;
```

```C++
export module mod;
import "std.hpp";
static_assert(is<int&>);
```

```
mod.cpp:1:8: internal compiler error: Segmentation fault
    1 | export module mod;
      |        ^~~~~~
