<pre>Unigine engine based applications failing to run in mesa master. They used to
run fine before with environment variable:
export MESA_EXTENSION_OVERRIDE="GL_EXT_framebuffer_multisample"
Tested applications:
Unigine Tropics-1.3
Unigine-Heaven-3.0
OilRush-1.12
console output after crashing of each application:
Tropics:
../../../../../../../src/mesa/drivers/dri/i965/brw_vec4_generator.cpp:1043:
void brw::vec4_generator::generate_vec4_instruction(brw::vec4_instruction*,
brw_reg, brw_reg*): Assertion `brw->gen >= 6' failed.
Aborted (core dumped)
My guess, it is due to the same bug,

The 74911 bug is resolved now fixing many applications but not unigine based
games on GM 45.
