Cpu mining error related to boost and mutex, many times now on exit

on an i7 930 intel chip, 8 gig ram, ubuntu server 16.04 LTS. Also happens on 16.04 LTS Desktop version.

zcashd: /home/debian/build/zcash/depends/x86_64-unknown-linux-gnu/share/…/include/boost/thread/pthread/recursive_mutex.hpp:113: void boost::recursive_mutex::lock(): Assertion `!pthread_mutex_lock(&m)’ failed.
Also, a version number on the splash screen would be nice :slight_smile:

Please let me know if this can be resolved. Thanks.
