            Bug ID: 20990
           Summary: [C++11] member pointer declaration cannot use decltype
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org
          Reporter: kariya_mitsuru at hotmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The sample code below should be compiled successfully but it causes compilation
error by clang.
struct S {
    int i;

int main()
    S v;
    int decltype(v)::*p = &S::i;

The "decltype(v)::*" is ptr-operator and "decltype(v)::" is
nested-name-specifier, so it is well-formed.
