### Description see #3563

Sorry about this lot but they all look different in a maybe related sort of way but after 6 bug reports and more coredumps than that, I shall stop now in the hope that there's some useful info somewhere in it all!

I started this experiment using 5.6.4 and that crashed 50 times in the space of 10 minutes so 5.7.1 is positively stable with just 6 coredumps in 3 hours!
