[Discuss-gnuradio] Crash on UHD import on a fresh build of 3.7.10 using PyBOMBS

[Eugene Grayver]

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.
