We are able to trigger a crash when we use --single-transaction with mysqldump. We tracked the issue down to the setting 'log_bin'. When removing 'log_bin' from the my.cnf we crash mysql by using this command:
mysqldump -u user --single-transaction mysql > mysql.sql
mysqldump: Couldn't execute 'START TRANSACTION /*!40100 WITH CONSISTENT SNAPSHOT */': Lost connection to MySQL server during query (2013)
When 'log_bin' is enabled in the my.cnf, it does not trigger the crash. Enclosed document contains the stack trace from the mysqld log.
