Comment 26 for bug 1657256

I have verified the package from -proposed, and it indeed fixes the bug.

I first deployed percona-xtradb-cluster-server from trusty-updates:

root@mario-trusty-percona-sru-verification:~# apt-cache policy percona-xtradb-cluster-server
percona-xtradb-cluster-server:
  Installed: 5.5.37-25.10+dfsg-0ubuntu0.14.04.2
  Candidate: 5.5.37-25.10+dfsg-0ubuntu0.14.04.2
  Version table:

Then I run sysbench tests from the control node, and percona crashed, as expected (and explained in this bug):

I then enabled -proposed pocket and upgraded percona packages:

And re-run the sysbench from the controll node, which now completed without an issue:

Package in -proposed indeed fixes the issue.
