	* testsuite/23_containers/array/tuple_interface/
	tuple_element_debug_neg.cc: Adjust dg-error.
	* testsuite/23_containers/list/operations/78389.cc: Fix less-than to
	define a valid strict weak ordering.
	* testsuite/23_containers/priority_queue/67085.cc: Disable test for
	Debug Mode, due to debug checks making extra copies of predicate.
	* testsuite/ext/pb_ds/regression/priority_queue_binary_heap-62045.cc:
	Likewise.
