            Bug ID: 30266
           Summary: [CWG 909] C-style cast necessitating static_cast ->
                    const_cast fails for conversion operator
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++14
          Assignee: unassignedclangbugs at nondot.org
          Reporter: r.hl at gmx.net
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

struct S {
  operator const int* ();
};

void f(S& s)  {
  const_cast<int*>(static_cast<const int*>(s));  // #1
  (int*) s;  // #2
}

#2 is intended to be valid (see core issue 909), yet fails to compile.
