--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-11-21 11:08:46 UTC ---
Reduced testcase:
struct P
{
  P () = default;
  explicit constexpr P (int x) : p (x) {}
  int p;
};

struct Q
{
  constexpr Q () : q (0x7f) {}
  int q;
};

struct R
{
  Q q;
  P p;
};

void
foo (R *x)
{
  *x = {};
}

Started ICEing with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=177997
