<pre>I believe that clang should ignore the problematic destructor in this template.
```
#include <type_traits>
struct Foo {
~Foo() {}
};
template <typename T>
struct Bar {
~Bar() requires( std::is_trivially_destructible_v<T>) = default;
~Bar() requires(!std::is_trivially_destructible_v<T>) {}
};
Bar<Foo> bar; // <-- picks `= default` and fails
```
Working example at <a href="https://godbolt.org/z/q5Phd1">https://godbolt.org/z/q5Phd1</a>. Clang _does_ do this properly
on the default constructor side of things.</pre>
