Jason Merrill asked for that during patch review: https://gcc.gnu.org/pipermail/gcc-patches/2025-July/688997.html "This will work for any class type with a what() method, which is different from vterminate.cc that only calls what() for a type derived from std::exception. I think it makes sense to be consistent with that; a what() from an unrelated class might mean something different."
