From 03f8a97d718502f60d16000aead251d88a751149 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 16 Mar 2012 09:31:13 -0600 Subject: [PATCH] st/mesa: add null pointer check in st_texture_image_map() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If we failed to allocate a memory resource for the texture we'd crash when we tried to map it. Now we propogate the NULL back up to the texstore code and generate GL_OUT_OF_MEMORY. Fixes a crash with the upcoming piglit max-texture-size test. NOTE: This is a candidate for the 8.0 branch.
