Hi, Thanks for testing this and for the simple SQL reproducer!
I also reproduced this issue under TPC-C workloads without using injection points. It's nice to have a smaller, self-contained reproducer that makes the issue easier to investigate and verify. The results with v5 are encouraging. The reproductions on 18.1 and 18.4 also confirm that released versions are affected, which will help make the case for back-patching once the fix is committed.
