Hi all!

I just found the line in the subject in our jenkinsbuild  log in both
amd64 and i386 case (we don't modified these files):

http://nyi-01.build.hardenedbsd.org:8180/jenkins/job/HardenedBSD-master-i386/56/console
http://nyi-01.build.hardenedbsd.org:8180/jenkins/job/HardenedBSD-master-amd64/58/consoleFull

And more similar lines:
