Subject: Change pp_lock to take a reference instead of a
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=5a47f09b1f37ad670eb23486a6efdb4c448efdfa;p=p5sagit%2Fp5-mst-13.2.git

Change pp_lock to take a reference instead of a
scalar since it wouldn't fork for the HELEM/AELEM
case. This was reported in bug #10045
