Indeed, GIMPLE_WITH_CLEANUP_EXPR in the IL after gimplification.
On the trunk this ICEs too, with type verification failure.
Distilling a testcase.

Simplified testcase:
struct M
{
  M () {}
  ~M () {}
};

struct S
{
  S ();
  M m[1];
};

S::S () : m ((M[1]) { M () })
{
}

This ICEs since somewhen between r134096 and r134281, likely PR35708.

ctor initializer isn't needed, this ICEs as well:
struct M
{
  M () {}
  ~M () {}
};

void
foo ()
{
  M m[1] = (M[1]) { M () };
}

and the ICE on the trunk is for the same reason, GIMPLE_WITH_CLEANUP_EXPR left
in the IL during gimplification, presumably because there wasn't any
immediately surrounding CLEANUP_POINT_EXPR.

Seems this is cleanup of the finish_compound_literal returned TARGET_EXPR vs.
TRY_BLOCK added by build_vec_init for the from_array != 2 case.
The TARGET_EXPR with cleanup is only referenced from within stmts inside of the
TRY_BLOCK, yet the corresponding CLEANUP_POINT_EXPR is only added outside of
the TRY_BLOCK and thus gimplification doesn't find the
GIMPLE_WITH_CLEANUP_EXPR.
