This works fine in 8.0.5 so I did a regression test, but there were some build
failures:
There are only 'skip'ped commits left to test. The first bad commit could be
any of: 23f1e551cc6553ce7f99b9264efc8776f5f35b00

We cannot bisect more!
However almost all of them are build fixes, or some gbm stuff which leaves:

This is with an old intel prescott cpu, 32 bit Fedora 17:
from /proc/cpuinfo
vendor_id : GenuineIntel
cpu family : 6
model : 14
model name : Genuine Intel(R) CPU T2300 @ 1.66GHz
printed with GALLIUM_DUMP_CPU=1
util_cpu_caps.nr_cpus = 2
util_cpu_caps.x86_cpu_type = 6
util_cpu_caps.cacheline = 64
util_cpu_caps.has_tsc = 1
util_cpu_caps.has_mmx = 1
util_cpu_caps.has_mmx2 = 1
util_cpu_caps.has_sse = 1
util_cpu_caps.has_sse2 = 1
util_cpu_caps.has_sse3 = 1
util_cpu_caps.has_ssse3 = 0
util_cpu_caps.has_sse4_1 = 0
util_cpu_caps.has_sse4_2 = 0
util_cpu_caps.has_avx = 0
util_cpu_caps.has_3dnow = 0
util_cpu_caps.has_3dnow_ext = 0
util_cpu_caps.has_altivec = 0
It seems this is highly cpu dependent, as this test doesn't crash on my other
machine (core2) with 64bit fedora ( there is just hang forever in
__lll_lock_wait() from libpthread.so.0 on exit )</pre>
