Igor,
After running volk_profile, can you retry your GRC program? It looks
like what's happening is that because your processor is so old, there
are no Volk kernels available for it, so it only has the 'generic'
version to run at any time. If you open up $(HOME)/.volk/volk_config,
it should be filled with "<kernel> generic' to tell the volk library
to only every run a generic kernel.

If that's still not working for you after volk_profile has run, then
something with that processor is confusing Volk. Otherwise, the bug in
the post you pointed towards with the volk_32fc_x2_multiply_32fc_a has
been fixed and the output of your GDB here isn't really telling me
anything. We'll have to look deeper.

Thanks,
Tom
