Reduced:

template 
struct vec
{
  struct { T y; };
  vec() = default;
};

template 
struct S
{
  vec value[2];
  template
  constexpr S(const U&);
};

template
template
constexpr S::S(const X&)
{
  value[0] = vec();
}

Sm(0);

Indeed.  The VOID_CST elts of the CONSTRUCTOR come from the
8352  if (is_dummy_object (argarray[0]))
8353return force_target_expr (DECL_CONTEXT (fn), void_node,
8354  no_cleanup_complain);
that patch added, and the constexpr handling code is upset that there is a
VOID_CST rather than CONSTRUCTOR inside of the elts.

PR c++/87075 - ICE with constexpr array initialization.

My patch of 2016-08-26 to avoid calling a trivial default constructor
introduced TARGET_EXPRs initialized with void_node to express trivial
initialization.  But when this shows up in a VEC_INIT_EXPR, we weren't
prepared to handle it.  Fixed by handling it explicitly in
cxx_eval_vec_init_1.

* constexpr.c (cxx_eval_vec_init_1): Handle trivial initialization.
