volk_malloc was introduced in 3.7.3 and is now relied upon by many GNU
Radio blocks and functions. What you're seeing here suggests that you have
multiple versions of GNU Radio installed and are linking against the wrong
version somewhere. Make sure you only have one version of the library
installed. Probably just clean up any installed libraries, header files,
and Python files and re-install. Using apt-get install gnuradio will get
you a working version.
