Well, after a few
restarts, here is my output. I did a fresh pull from git
because I was getting some errors with missing *.h files in
gruel/src/swig or something like that. Hope this helps!
Program received signal SIGSEGV, Segmentation fault.

Alright, Fred, definitely something strange going on here.
My only guess is that for some reason on your
architecture/OS/whatever, something is being handled
incorrectly and the buffers a, b, and c are not getting
generated correctly, maybe something like it's not doubling
the number of items for the complex data type (before this
function test, there are 16ic, or complex shorts, being
tested, but this is the first complex float test).
It's hard to tell if it's something about it being an AMD
chip, 32-bit, Slackware version, gcc version, etc. And I don't
have an AMD chip to test on, but I could load up a 32-bit
Slackware VM at least.
How much work are you willing to put into this to help us
nail this down?
If you can follow through the volk_profile test code, we
can start outputting more debug info. To start with, I'd
suggest going into volk/apps/volk_profile.cc and commenting
out line 38, rebuild the application, and run this new
volk_profile to see if it fails on any other kernels.
