From 0458224743337acef025f53da01beb46eacd4493 Mon Sep 17 00:00:00 2001 From: Timur Pocheptsov Date: Mon, 18 Apr 2016 12:31:49 +0200 Subject: Avoid nullptr deref in Q_ASSERTS Found by Coverity, CIDs: [159014-159383]. Indeed, Q_ASSERTS can go into the block controlled by the corresponding if-statements, otherwise - why 'if' at all?
