Can you please test 3.17.4-r1 which I put on the tree tomorrow.  It should fix this problem.  I will then rapid stabilize it.
Comment 2 Anthony Basile gentoo-dev 2014-11-29 13:13:24 UTC 
Did your patch make it into grsecurity-3.0-3.17.4-201411260107?  If so,  then this fix is in the tree with hardened-sources-3.17.4-r1.  I'd like to remove the earlier versions which have this issue.

This should be fixed in the latest stable.  Reopen if it isn't.
