Just rebuilt GR using pybombs (went very smoothly). However, encountered a
very weird bug -- segfault on 'from gnuradio import uhd'. The machine does not
have any UHD devices attached (have not yet checked what happens if there's in
fact a device). Here's a backtrace from gdb. Apparently something bad happens
in high_res_timer. I verified the system paths $LD_LIBRARY_PATH, $PYTHONPATH,
$PATH and they all point to the latest pybombs install.
I've never seen this one before... (after the backtrace, there's some more info)
Core was generated by `python -c from gnuradio import uhd'.
Program terminated with signal SIGSEGV, Segmentation fault.
