Wow, that's not good :-). I took a quick peek at the code but didn't spot 
anything obvious. Since I don't have time to investigate further now, perhaps it 
would be best to track this in the gitlab issue tracker

https://gitlab.com/libvirt/libvirt/-/issues

Can you create a new issue there? Thanks!

Jim
