--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Ah, we have:
case TARGET_EXPR:
if (TARGET_EXPR_INITIAL (stmt)
&& TREE_CODE (TARGET_EXPR_INITIAL (stmt)) == CONSTRUCTOR
&& CONSTRUCTOR_PLACEHOLDER_BOUNDARY (TARGET_EXPR_INITIAL (stmt)))
TARGET_EXPR_NO_ELIDE (stmt) = 1;
break;
but that doesn't trigger in this case because the TARGET_EXPR's CONSTRUCTOR
is not CONSTRUCTOR_PLACEHOLDER_BOUNDARY, instead it is a CONSTRUCTOR that
contains a CONSTRUCTOR_PLACEHOLDER_BOUNDARY CONSTRUCTOR as one of its elements.
