      All threads' stack traces are attached.
      Binary logs from master are attached.

      It happened once so far during tests on Power.
      The test was run with ~64 threads on master, SBR, 8 slave parallel threads, thread_handling=pool-of-threads. Here is the complete RQG command line (for informational purposes, it does not necessarily reproduce the issue):
