Crash in row_search_mvcc() probably related to secondary index corruption

This could be because you hit a bug. It is also possible that this binary

or one of the libraries it was linked against is corrupt, improperly built,

or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help

diagnose the problem, but since we have already crashed, 

something is definitely wrong and this may fail.

key_buffer_size=33554432

read_buffer_size=1048576

max_used_connections=74

max_threads=2010

It is possible that mysqld could use up to 

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 10348902 K  bytes of memory

Hope that's ok; if not, decrease some variables in the equation.
