Dawid Weiss commented on LUCENE-5212:
-------------------------------------
We inspected the code with Robert Muir and came to the conclusion that this bug
may also affect SSE machines. Since hotspot code is very complex I also
contacted Vladimir and he kindly replied that yes, this is the case.

And you are correct the problem also affects SSE for which we can generate 16
bytes vectors which are larger then 8 bytes stack frame alignment we have.
Actually in the bug there were only 16 bytes vectors max.
I think it may be related to register masks we use on AVX machine, they are
larger to be able map 32 bytes vectors. But again with SSE and 16 bytes vectors
you can hit the same 8024830 problem but may be much less frequent.
