From 149474c93490e1c66f838391bd491db83136d91d Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Mon, 3 Sep 2012 21:19:11 +0200 Subject: json-parser: Fix potential NULL pointer segfault Report from smatch: json-parser.c:474 parse_object(62) error: potential null derefence 'dict'. json-parser.c:553 parse_array(75) error: potential null derefence 'list'. Label 'out' in json-parser.c can be called with list == NULL which is passed to QDECREF. Modify QDECREF to handle a NULL argument (inline function qobject_decref already handles them, too).
