Yes, I also see this; my setup is Mac OS X 10.9 (Darwin Kernel Version 13.4.0, x86_64); Xcode 6.1
Build version 6A1052d "Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)". I'll also test on 10.8 soonish, and will be able to test on 10.11b3 sometime next week if all goes as planned / hoped.

Which protokernel is failing? SSE3, AVX, or both?

Hmm. Weird that it's only showing up on Apple machines since it looks close enough that it might just be a tolerance issue

Seems like it might be a rounding error?

Found the same issue on MSVC Windows 64-bit, but only on a_sse3.
volk_32f_x3_sum_of_poly_32f ... failed in arch a_sse3 ... offset 0 in1: 32611.7 in2: 32554.9 tolerance was: 0.001

Been a long time. Probably fixed by now.

With PR #112 in place, this issue is no longer relevant on Mac OS X 10.7 / 8 & 10.12 (latest) -- meaning that Volk passes "make test" cleanly. So, I think it can be closed if it's not already.
