Issuing a query that triggers a trigger on a timestamp field makes the mysql server go away.
Query are inside file query.log and syslog.log contain a trace.
You need two databases JosmWeb and josm_web, load JosmWeb with JosmWeb.Auction.schema.sql and JosmWeb.AuctionHasAuctionItems.schema.sql. Load josm_web with objlistaJosm.sql, run the update query inside query.log.
The same update query works in Oracle mysql-server-5.6 (and even back to 5.0).
Tested on clean install of both MariaDB 10.1 and MySQL 5.6.
