Assertion `!(thd->rgi_slave && thd-> rgi_slave->did_mark_start_commit)' failed in ha_rollback_trans



      Note: it's possible that 10.0 is also affected, I am currently running tests on 10.1, so it comes from there.

      Stack trace from 10.1 8ea9b8c0b168b3e5aad08886477d8726531abcd5

      Trying to get some variables.
      Some pointers may be invalid and cause the dump to abort.
      Query (0x7fbe260c8179): ROLLBACK
      Connection ID (thread ID): 11
      Status: NOT_KILLED

      To reproduce, start master with the attached binary log (default options will do), start slave with slave_parallel_threads=8, set up replication, wait.
