[ja...@apache.org]

Author: jailletc36
Date: Sat May 26 16:54:23 2018
New Revision: 1832317

URL: http://svn.apache.org/viewvc?rev=1832317&view=rev
Log:
Fix a potential un-intialized variable usage warning.
This can not be a runtime ixsue, because, in such a case, we would assert and abort before.

 PR 59819.
