Below is the test I use to reproduce it. However, the success seems to largely depend on the machine: I can reproduce it fairly easily on two very different machines, but can't reproduce it at all on two other machines, even after dozens of runs.
Unfortunately two machines where I can reproduce it can't run rr, so I have no information so far whether it can even be reproduced with rr.
