-Subject: [PATCH 12/13] Fix nullptr deref with XPath logic ops
-
-If the XPath stack is corrupted, for example by a misbehaving extension
-function, the "and" and "or" XPath operators could dereference NULL
-pointers. Check that the XPath stack isn't empty and optimize the
-logic operators slightly.
