It's a debug binary apparently..

#ifdef UNIV_DEBUG
      mtr_commit(&mtr);
      mtr_start(&mtr);
      ut_ad(btr_validate_index(index, 0, false));
      ut_ad(0);   <--------
#endif /* UNIV_DEBUG */

When only debug build is affected the Severity could be S6 (Debug Builds) just that.

Hi,

Can we please get a more precise information. Like, the exact sysbench command with all options, for how long to run, how to stop, how to restart etc.
