I guess maybe the following commit has helped to avoid bounce buff= er? https://cgit.freebsd.org/src/commit/?id=3De7a9817b8d328dda04069b65944ce2ed6= f54c6f0 Anyway, the patch looks good and it doesn't cause any regression on amd64 or arm64 according to my test. --=20 You are receiving this mail because: You are the assignee for the bug.=
