Bug#393704: interactive client dies on ill-timed SIGWINCH

[Ian Jackson <ian@davenant.greenend.org.uk>]

Package: openssh-client
Version: 1:4.3p2-3

I often ask my window manager to bring up `xterm -e ssh somehost'.  I
have the wm configured to allow me to interactively place resize the
window.  Sometimes, when I do this, the xterm and ssh vanish.  Process
accounting shows ssh dying with exit status 255.

I've spoken to other users and they report that this happens to them
sometimes too.

I suspect that the SIGWINCH arrives at a time when ssh is buggily
unable to cope with EINTR.

I realise that this report isn't particularly informative.  Please let
me know what additional tests/diagnostics you'd like me to do.
Unfortunately I can't reproduce the symptoms on demand; it happens to
me spontaneously about once every few weeks.  Any instrumentation
you want me to do would have to be reasonable to do for all of my ssh
sessions until the bug recurs, and would have to not affect the
timings significantly.

Ian.
