Dawid Weiss commented on LUCENE-5212:
-------------------------------------
I confirm that this patch fixes the problem. I've tested svn rev. 1523179
(trunk) against jdk8-b114 with and without Vladimir's patch. Without the patch
the test sequence ends about 50% of the time in a sigsegv. With the patch all
executions ended without any errors.
Note that the problem only affects CPUs with the AVX extension. A workaround
for affected VMs is to disable vectorization with -XX:-UseSuperWord.
