Thankyou for this bug report. The bug was tracked down to a missing case statement in the optimizer. We have a fix, and it will be checked-in for VS11.

Thanks,

Jim

There were problems uploading the file. I have uploaded it again.

The error seems to disappear when _mm256_extracti128_si256 is replaced with the almost equivalent instruction _mm256_extractf128_si256
