Trying 'dbx' to get a backtrace

Trying 'gdb' to get a backtrace from coredump /dev/shm/var/2/log/rocksdb_rpl.mdev12179-innodb,row,row/mysqld.2/data/core

Core generated by '/usr/sbin/mysqld'

Output from gdb follows. The first stack trace is from the failing thread.

The following stack traces are from all threads (so the failing one is

duplicated).
