Hello,
I do not believe this is a known issue.
The place that generates that diagnostic assert()s on failure, so hopefully
you have one or more core dumps available. The backtrace from the dump
(ideally with line numbers in libkrb5support, but even without) would be a
great place to start.
Thanks,
Ben
