This is OK for both mainline and the 4.0 branch. As this
regression manifests as a failure of 23_containers/deque/cons/2.cc
it doesn't strictly require an additional testcase, but feel free
to add your reduced testcase to g++.dg/opt at your discretion.
Many thanks for investigating and fixing this.
