--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

Maybe the bug is in gimplify_compound_literal_expr.

Here:
  /* Otherwise, if we don't need an lvalue and have a literal directly
     substitute it.  Check if it matches the gimple predicate, as
     otherwise we'd generate a new temporary, and we can as well just
     use the decl we already have.  */
  else if (!TREE_ADDRESSABLE (decl)
           && !TREE_THIS_VOLATILE (decl)
           && init
           && (fallback & fb_lvalue) == 0
           && gimple_test_f (init))
    {
      *expr_p = init;
      return GS_OK;
    }


There is no check on DECL_STATIC here.
