According to the upstream git commit logs, we've had the fix in 7.0-gnu
and in the stable branches when they got them, which seems to have been
a few weeks ago as well: 6.19.12-gnu, 6.18.22-gnu.

Other stable branches were fixed only in the latest batch of updates:
6.12.85-gnu, 6.6.137-gnu, 6.1.170-gnu, 5.15.204-gnu, 5.10.254-gnu1.

This is based exclusively on whether or not the upstream releases
contain commit a664bf3d603dc3bdcf9ae47cc21e0daec706d7a5 or backports
thereof.
