--- Comment #1 from Kristof Provost <kp at freebsd.org> ---
Thanks for the report.

This is very likely the same issue as bug #201879. A corruption of the fragment
cache (a freed element not being removed from the list/tree).

I've not yet been able to reproduce this myself, and I can't figure out how it
might happen from simple code reading.

Knowing that it's related to the v4 path is useful though.
