Hi! I use FreeBSD 11 (clang 3.8) and openssh-portable-7.3.p1_1,1 libressl-2.4.3 (build from ports, openssh only PAM option enabled) and custom configs (see attach).
On amd64 - all OK. On i386 after I connect and enter password ssh client disconnect and in server log: pid 19660 (sshd), uid 0: exited on signal 4 signal 4 = illegal instruction. I do small investifation and found that if I remove RekeyLimit 1G 30d from sshd_config or set RekeyLimit 1G or RekeyLimit 1G 1h or RekeyLimit 1G 24d then all OK. 25d and more - fail. Looks like some where int variable with seconds overflow.
