From: Neha Bhende Date: Mon, 22 Jan 2018 23:01:20 +0000 (-0800) Subject: svga: Check rasterization state object before checking poly_stipple_enable X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e4ca1d64565b4d665bcaf5d08922bfbe1d920e7a;p=mesa.git svga: Check rasterization state object before checking poly_stipple_enable Sometimes rasterization state object could be empty. This is causing segfault on hw8,9,10 for some traces. This patch fixes enemy_territory_quake_wars_high, enemy_territory_quake_wars_low, etqw-demo, lightsmark2008, quake1 glretrace crashes on hw 8,9,10. Tested with mtt-glretrace and mtt-piglit.
