2020-02-06T12:35:13.5507574Z This could be because you hit a bug. It is also possible that this binary

2020-02-06T12:35:13.5507817Z or one of the libraries it was linked against is corrupt, improperly built,

2020-02-06T12:35:13.5508047Z or misconfigured. This error can also be caused by malfunctioning hardware.

2020-02-06T12:35:13.5509233Z We will try our best to scrape up some info that will hopefully help

2020-02-06T12:35:13.5509469Z diagnose the problem, but since we have already crashed, 

2020-02-06T12:35:13.5509695Z something is definitely wrong and this may fail.
