    Description

      I just have got one of Galera nodes crashed, probably on "drop database" statement. Also this crash caused to Galera SST recovery, not IST, here is part of recovery log:

               at galera/src/replicator_str.cpp:prepare_for_IST():482. IST will be unavailable.
      

      Here is error report:

      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.
       
      Server version: 10.1.23-MariaDB
      key_buffer_size=134217728
      read_buffer_size=1048576
      max_used_connections=38
      max_threads=2049
      thread_count=26
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 6487237 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
      information that should help you find out what is causing the crash.
       
      We think the query pointer is invalid, but we will try to print it anyway.
