Hi Matthew,

Thanks for the report. Unfortunately I cannot replicate this with
either 2.0.1 or latest master (on a non-Ubuntu x86-64 Linux). It also
passes ok on our 14.04 CI systems. Is this crash consistent for you?
Are you using the stock 16.04 GCC?

A simple backtrace, even without debug symbols, might be enough to
deduce the problem.

Jack
