I built Tom’s safe_align branch on E100 and ran volk_profile. It segfaulted on “RUN_VOLK_TESTS:volk_32fc_s32fc_multiply_32fc_a. I’ll get a stack trace for you.

Thanks for the inputs!
Run volk_profile. It does exactly what you said, and writes the results to ~/.volk/volk_config. Volk reads this file when it is involked (sorry) to determine which particular function to execute. So all you do is run volk_profile once on any given machine, and it's optimized.
This is discussed on the webpage:
We'll be updating this as things progress with Volk, but the profiler info is there already.
