            Bug ID: 106830
           Summary: [bisected] 32 bit tests (deqp, piglit, glcts,
                    vulkancts) crashing on all platforms
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW

deqp, glcts, piglit, and vulkancts tests are all crashing when run with 32 bit
Mesa.This seems to affect every platform except G33.


This has been bisected to this commit:

    intel/eu: Switch to a logical state stack

    Instead of the state stack that's based on copying a dummy instruction
    around, we start using a logical stack of brw_insn_states.  This uses a
    bit less memory and is way less conceptually bogus.
