    Details

      Description

      Note: The test case is non-deterministic, run with a high value of --repeat=N. It usually fails for me one or another way withing 100 attempts (they are very fast, it takes less than a minute to run 100), but it can vary a lot on different machines and builds. You can also try to change the number of inserted values in the test case, it may affect the outcome as well.

      Non-debug build doesn't crash, but it has been seen to fail on the provided test case in an odd way:

      Which of course shouldn't be happening.

      A similar test case, only differs from the previous one in the number of inserted rows. More readily fails on a different assertion:
