This is what gdb spits out (without debug symbols):

Program received signal SIGILL, Illegal instruction.
0x00007ffff7b4cd40 in volk_16ic_s32f_deinterleave_real_32f_a_sse4_1 ()
from /rw/home/user/gnuradio/gnuradio/volk/build/lib/libvolk.so.0.0.0
Missing separate debuginfos, use: debuginfo-install
boost-test-1.46.0-3.fc15.x86_64 glibc-2.14.1-6.x86_64
libgcc-4.6.3-2.fc15.x86_64 libstdc++-4.6.3-2.fc15.x86_64
orc-0.4.16-5.fc15.x86_64

What's the recommended way to build volk with debug symbols using cmake?
Sorry, I don't have much experience with cmake...
