commit 8a33cdeba4ba032f3d0efebf230b86971c27e158
Author: Norihiro Tanaka <address@hidden>
Date:   Tue Aug 11 00:37:00 2015 +0900

    grep: avoid use of uninitialized variable
    EGexecute would use "backref" uninitialized.
    While that could have no bearing on correctness, it could
    impact performance, via an unnecessary use of regexp.
    * src/dfasearch.c (EGexecute): Initialize backref.
    Reported as
    Introduced by commit v2.21-55-gea0ebaa.
