Another testcase, this one ICEs:

// PR c++/49136
// { dg-do compile }
// { dg-options "-std=c++0x" }

struct S
{
  unsigned : 1; unsigned s : 27; unsigned : 4;
  constexpr S (unsigned int x) : s(x) {}
};

struct T
{
  unsigned int t;
  constexpr T (S s) : t(s.s != 77 ? 0 : s.s) {}
};

constexpr S s (77);
constexpr T t (s);
static_assert (t.t == 77, "Error");
