Hello, I'm getting the invalid opcode exception whenever the volk
library is used from gr/grc. It is also easy to reproduce by executing
volk_profile:
address@hidden gnuradio]$ volk_profile
Using Volk machine: avx_64
RUN_VOLK_TESTS: volk_16ic_s32f_deinterleave_real_32f_a
Illegal instruction
address@hidden gnuradio]$ dmesg
[ 6920.211094] volk_profile[25627] trap invalid opcode ip:7f8145b74d40
sp:7fff41dfac78 error:0 in libvolk.so.0.0.0[7f8145ad7000+cf000]
I tried v3.5.2 and v3.5.2 build directly from git, using the building
script from here:
http://gnuradio.org/redmine/repositories/changes/gnuradio/README
Here's my cpuinfo:
address@hidden gnuradio]$ cat /proc/cpuinfo

And, FWIW, this is the autoconfig snippet:

One more thing to note that I'm running in a Xen PV VM, although this
should not matter, as the usermode instructions execute directly on the
CPU in this mode.
Thanks,
joanna.
