Also, when reporting bugs, especially on an ARM chip and with things
that might be VOLK related, please tell us the version of GNU Radio
you are using. If you are cloning via git, let us know the current
revision. There's work going on to address issues related to ARM and
VOLK on certain platforms, so that could make a big difference.
