9 use of $' slows down all regexp matches - ID: 1645290

Last Update: Comment added ( coral )

Details:

Hi guys, Justin here from SpamAssassin.

Just came across a bit of a problem with razor-agents 2.82 -- there are a
few places where it uses the forbidden $' perlvar, which, as 'perldoc
perlvar' states, is bad news for regexp performance:

The use of this variable anywhere in a program imposes a
consider-
able performance penalty on all regular expression matches.
See
"BUGS".

patch to follow.
