I'm running into similar issues.
I'm also a little confused by my ctest output because it seems to indicate that Volk is selecting the failed alignments as the "Best aligned arch[s]".
Here's my set up:
Intel® Core™ i7-5600U CPU @ 2.60GHz × 4
Ubuntu 14.04 LTS
GNURadio (v3.7.9) @ git commit dec480ab3f0809677ba3ef2a3a64d402d742b5ec
Volk @ git tag: v1.2
Output of ctest -V (after running make on GNU Radio):

This is a side-effect of actually fixing the implementations (#52 (comment)). Some branch merging accidentally overwrote the fix. It should no longer fail QA, but kernel behavior has not changed
