           Summary: no diagnostic for uninstantiatable template
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com


The following template cannot be instantiated:

template<typename T> struct S { S() { void f(int); f(T(), T()); } };

The block-scope declaration of 'f' disables ADL, so the call to 'f' will never
work.

clang provides no diagnostic for this.
