[Bug]: openssh: KnownHostsCommand fails with signal 31

[SeerLite]

Problem description

Trying to connect via ssh with KnownHostsCommand option set to any valid program makes ssh always fail with the following error:

KnownHostsCommand-ORDER <command> exited on signal 31
KnownHostsCommand failed

What steps will reproduce the bug?

ssh -o KnownHostsCommand='/usr/bin/env true' localhost -p 8022

or more directly:

ssh -o KnownHostsCommand='/bin/true' localhost -p 8022

(or you could ssh to any valid addres/port with the option set)

What is the expected behavior?

ssh connects normally. This can be proved on a Linux desktop.
