<pre>
    Clang crashes with a TypeLocBuilder assertion when run on this code (https://godbolt.org/z/or16hfTzf), no other command line options necessary:

```
template <int AS>
using ASPtrTy = void [[clang::address_space(AS)]] *;

template <int AS>
struct EntryTy {
    ASPtrTy<AS> Base;
};
```
> clang::TypeLoc clang::TypeLocBuilder::pushImpl(clang::QualType, size_t, unsigned int): Assertion `TLast == LastTy && "mismatch between last type and new type's inner type"' failed.
