Affected version:
2.29.51.20170921 and maybe past releases


As best as I can see, it looks like the bug was introduced after the
2.28 series was frozen/split-off, and there is no part of the patch that
applies to the 2.28.1 release.

I have not, however, tried the reproducer.


The provided testcase works for me after the commit
