In a previous post, I talked about the existence of a CREATE TABLE that is crashing MySQL up to versions 5.5.58, 5.6.38 and 5.7.20, and MariaDB up to version 5.5.57, 10.0.32, 10.1.26 and 10.2.7. I hope you upgraded (or can mitigate this problem in another way) as I am now publishing the CREATE TABLE of death.
