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. --=20 You are receiving this mail because: You are the assignee for the bug.=
