<pre>In the following example, the using declaration is incorrect since it refers to
a non-existent class. Clang attempts to typo-correct this, but the correction
is a function instead of a class. This later triggers an assertion.
$ cat test.cc
template <class T>
struct ptr {
ptr(T*);
};
namespace NS {
struct _First__End_ {
static ptr<_First__End_> New_SecondPart__End_();
};
} // namespace NS
using NS::_First__SecondPart__End_;
void run() {
ptr<_First__SecondPart__End_> un = _First__SecondPart__End_::NewInstance();
}
$ clang test.cc
