From 19f54b2d2539171f682bcf32cdc7983294355e02 Mon Sep 17 00:00:00 2001 From: Martin Banky <Martin.Banky@gmail.com> Date: Thu, 15 Oct 2015 23:07:32 -0700 Subject: [PATCH] Scene Graph: Fixed memory leak in QSGBatchRenderer::Renderer::map() In the uncommon case (m_context->hasBrokenIndexBufferObjects() || m_visualizeMode != VisualizeNothing) of mapping a buffer, malloc is called without first freeing the previous malloc.
