Bug Description

[impact]

pacemaker's attrd may segfault on exit.

[test case]

this is a follow on to bug 1871166, the patches added there prevented one segfault but this one emerged. As with that bug, I can't reproduce this myself, but the original reporter is able to reproduce intermittently.

[regression potential]

any regression would likely impact the exit path of attrd, possibly causing a segfault or other incorrect exit.

[scope]

this is needed only for Xenial.

this is fixed upstream by commit 3c62fb1d0d which is included in Bionic and later.

[other info]

this is a follow on to bug 1871166.
