             Bug #: 13520
           Summary: -Wunused-private-field false positive after error
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk
                CC: djasper at google.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

This code triggers a -Wunused-private-field false positive on C::S::k:

class C {
  struct X {
    int n;
  } x;

  class S {
    int k;
    C *p;
    S(int k, C *p) : k(k), p(p) {}
    void f() { p->x.n = k; }

  void f(UnknownTypeName utn);

I guess we're setting C to be invalid, and so discarding the use of 'k' within

(To see this in the wild, introduce a bad type name into any Sema member
function declaration...)
