You can get more info out of the client by adding -oLogLevel=debug3 to
both ssh and sftp command lines and comparing them.  If you do, please
use "Add an attachment" to attach both logs to this bug so we can take
a look.

sftp invokes ssh and must consume its output, once that pipe is full
ssh will block until sftp does.  I suspect the different is due to a
race: without that blocking ssh initiates the close first, and with the
blocking the server crashes/exits before ssh gets around to closing the
connection.  If that's the case there's not much OpenSSH can do.
