<div>
<pre>This code crashes the clang frontend.
```
struct I {};
template<const I&>
void func() {}
auto testFunc() {
return func<I{}>(); // crash
}
```
It's the same for struct/classes. See: <a href="https://clang.godbolt.org/z/W-izMz">https://clang.godbolt.org/z/W-izMz</a>
The expected behavior:
* clang does not crash
* correct diagnostics message</pre>
