--- Comment #8 from Kristof Provost <***@freebsd.org> ---
I was going to ask you to confirm that it's really the pf scrub code that does
this, but I've got a test case using epair that appears to demonstrate the
problem as well.

So the good news is that it is trivially reproducible, and that we'll have a
test case to prevent regressions when we fix this.

Test case: https://reviews.freebsd.org/D30013

I'm hopeful that I'll be able to dig into the actual cause tomorrow.
