Subject: bug#21273: [PATCH] grep: avoid use of uninitialized variable
Date: Sun, 16 Aug 2015 11:17:52 +0900

[Message part 1 (text/plain, inline)]

Uninitialized value of variable BACKREF is referred in EGexecute.  It
does not cause wrong result, but regex may be used even when it is not
needed.  It may lead grep to slowdown.

By the way, gawk initializes the variable already, so it does not have
to be fixed.
