            Bug ID: 17224
           Summary: MSVC allows incomplete types as template params
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: david.majnemer at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

consider:

template <class T>
struct InherType : public UndefType {};
template <class T>
class TmplType {};
TmplType<InherType<wchar_t> > x;

MSVC is fine with this even though InherType inherits from a previously
unreferenced type.

Once you try to use the incomplete type, diagnostics are emitted.
