I'm having similar issues with gnuradio git commit
523a53ac387a699cef4d8e784561cdcaffad39cf as well as 3.7.0. I have run this
test multiple times (the very first failure was at shmat (2)). Gnuradio was
natively compiled with gcc 4.6.3 for the ARM Coretex-A9 (Xilinx Zynq)
processor. Now, surprisingly, when running the unit tests under qemu-user
chroot as described here: 

http://www.gentoo.org/proj/en/base/embedded/handbook/?part=1&chap=5

it seems to work fine.

Here is a snapshot of running ctest -V -R gr-runtime on the ARM processor:
