Subject: mdocml: Even after switching from a pending head to the body, we have to
Date: Thu, 11 Aug 2016 08:30:55 -0500 (EST) [thread overview]
Message-ID: <16937554755328550823.enqueue@fantadrom.bsd.lv> (raw)
Log Message:
-----------
Even after switching from a pending head to the body, we have to
continue scanning upwards, because the enclosing block might already
be pending as well, e.g. .Bl .Bl .It Bo .El .It.
Tree corruption leading to a later NULL deref found by tb@ with afl(1).
