These are unrelated to your issue. I used a feature from recent versions of gcc (-fsanitize=address) to track another problem and as a side effect it revealed many memory leaks. I fixed some easy ones but many other remain.

The one from "analyze rolls" is not among them but limiting the analysis depth to 4 instead of 5 decreased its maximum cost by a factor of 21. That should be enough to prevent the kind off crash you experienced in practical usage.

There's no need for depth 5 ... and it is not available anymore: 4 is the
max today. I don't know when or where it is changed, but is after May 12
and before May 29.
