--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I no longer get any crashes here:

$ xg++ -c -std=c++20  87536.C
87536.C:2:6: error: C++20 concept definition syntax is ‘concept <name> =
<expr>’
    2 | bool concept X = X<T>;
      |      ^~~~~~~

$ xg++ -c -std=c++17  87536.C -fconcepts-ts
cc1plus: note: ‘-fconcepts-ts’ is deprecated and will be removed in GCC 15;
please convert your code to C++20 concepts
