Clang crashes on the following code (https://godbolt.org/z/KcoqrEME7) since 19.1.0:
```cpp
template <typename T> struct A { A(T); };
template <typename T, template <typename> class TT = A>
using Alias = TT<T>;
template <typename T>
using Alias2 = Alias<T>;
void h() { Alias2 a(42); }
void h2() { Alias a(42); }
```
