Not sure if this is the right place to post this but I have had this error with 3.5.2 and later (git and on Slackware 13.37 on a dual athlon 32 bit machine. The problem is not present on an Intel Atom (32 bit dual core) machine with exactly the same configuration and libraries installed. Here is the python error report from gnuradio-companion:

Executing: "/home/fred/gnuradio/top_block.py"

Using Volk machine: generic
Traceback (most recent call last):
  File "/home/fred/gnuradio/top_block.py", line 169, in <module>
    tb = top_block()
  File "/home/fred/gnuradio/top_block.py", line 101, in __init__
    self.gr_multiply_xx_3 = gr.multiply_vff(1)
File "/usr/lib/python2.6/site-packages/gnuradio/gr/gnuradio_core_general.py", line 8783, in multiply_ff
    return _gnuradio_core_general.multiply_ff(vlen)
RuntimeError: gr_block::set_alignment_multiple

When running volk_profile from the git sources, the application produces a segfault when it reaches volk_32fc_x2_multiply_32fc_a

I did a trace using ddd and it traced the error back to libvolk.so.0.0.0
