Hello, I am seeing segfault crashes from knot + libknot7 version 2.6.8-1~ubuntu for amd64, during a zone commit cycle. The transaction is empty by the way, but in general we use a utility to compare Ist to Soll.
This came up while editing a zone that hasn't been configured yet, so we are obviously doing something strange. (The reason is I'm trying to switch DNSSEC on/off in a manner orthogonal to the zone data transport, which is quite clearly not what Knot DNS was designed for. I will post a feature request that could really help with orthogonality.) I'll attach two flows, occurring virtually at the same time on our two machines while doing the same thing locally; so the bug looks reproducable. If you need more information, I'll try to see what I can do.
