C++ parser crashes on this illegal code:

struct S {
  S() : i(0) {}
  int i;

  void f() {}
};

void f() {
  S cs;
  int S::*pm = &S::i;
  cs.*pm = 1;

  void S::(*pf)() = S::f;
  (*pf)();
}

$ clang -cc1 -x c++ ptr-to-member.cpp

clang:
/home/xzx/llvm/tools/clang/lib/Parse/../../include/clang/Parse/Parser.h:1947:
void clang::Parser::DeclaratorScopeObj::EnterDeclaratorScope(): Assertion
`!EnteredScope && "Already entered the scope!"' failed.
