             Bug #: 13293
           Summary: 'auto' prematurely deduced if the declarator is
                    dependent
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk

This is valid code, which should deduce *p's return type:

int f(int);
template<typename T> struct S {
  static constexpr auto (*p)(T) = &f;
};

Clang diagnoses it:

error: variable 'p' with type 'auto (*const)(T)' has incompatible initializer
of type 'int (*)(int)'
  static constexpr auto (*p)(T) = &f; };
                          ^       ~~
