      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.

      Fatal signal 11 while backtracing
      

      The test fails since 10.4.19 when it was added.
      It may not fail in buildbot and other multi-test runs because some next tests in the chain may hide the failure. For example, in 10.4 buildbot innodb.alter_copy does the trick (by killing the server):

      worker[1] Using MTR_BUILD_THREAD 300, with reserved ports 16000..16019
      gcol.virtual_index_drop 'innodb'         [ pass ]     70
      innodb.alter_copy 'innodb'               [ pass ]  14181
      --------------------------------------------------------------------------
      The servers were restarted 0 times
      Spent 14.251 of 17 seconds executing testcases
       
      Completed: All 2 tests were successful.
      

      There are likely other tests which do the same.
