      On my VM it seems simple enough to see the error by doing:
      (10.6 af552f2903b9764e3bc0634a0037c39d1a837f4f)

      ./mtr rpl.rpl_mdev10863 --parallel=auto --repeat=20

            I tested a WITH_UBSAN build of 10.7 before and after the merge MDEV-29322:

            ./mtr --parallel=60 --big-test --force

            Before the merge, one test failed related to this:

            After the merge, there was no such failure. I tried the test run twice. The only failures are something unrelated:

            I believe that this is basically a duplicate of MDEV-29322.
