Yes, it does get called at "make check" time.
FWIW, it's run by way of gnuradio-core/src/tests/test_all
It's possible that there's an alignment requirement that's not being
honored at runtime. The low-level SSE code (fcomplex_dotprod_sse64.S)
requires that its input and taps be 16-byte aligned. gr_fir_ccf_simd
allocates 16-byte aligned buffers for the relevant buffers, so it
should be working OK. Perhaps one of you seeing the problem could
add an assert or two to confirm that the alignment is correct.
