Description
Note: reproducible on the current 10.1 tree commit 476dfb1603 plus the patch for MDEV-8164 applied locally (either 6f1114b or eefada5, all the same). The stack traces below are from the latter patch on top of 10.1 tree.
The two failures below happen intermittently on the same test, which is why I am filing them together. I don't know if they have the same root cause or not.
