From 8bb291b0f59e8e13bc252cb35672eb468e53881a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 20 Feb 2013 07:39:04 -0700 Subject: [PATCH] st/mesa: check for dummy programs in destroy_program_variants() When we destroy an ARB vp/fp whose ID was gen'd but not otherwise used we get a pointer to the dummy/placeholder program. We can't destroy that one so just skip it. This only failed during context tear-down because glDeleteProgramsARB() was already aware of dummy programs. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=38086 Note: This is a candidate for the stable branches.
