From 0a5dff15912207b83018485f83e067474e818bab Mon Sep 17 00:00:00 2001 From: Li Qiang <liq3ea@gmail.com> Date: Thu, 5 Jan 2017 18:02:46 -0800 Subject: [PATCH] vrend: never destroy context 0 in vrend_renderer_context_destroy There will be a crash if the guest destroy context 0. As the context 0 is allocate in renderer init, not destroy in vrend_renderer_context_destroy. The context will be freed in renderer fini by calling vrend_decode_reset.
