Description
The test case is non-deterministic, run with --repeat=N. It usually fails for me within several attempts, but it can vary on different machines and builds. If it doesn't fail for you, also try to change the number of rows inserted into the table, it can affect the outcome.

SUMMARY: AddressSanitizer: 65504 byte(s) leaked in 1 allocation(s).

There is also a similar error with Aria observed in concurrent tests, although it's much less frequent, and I couldn't reproduce it by changing MyISAM to Aria in the test case above:
