scp: write stdout: Broken pipe error (Tru64 UNIX)

[John P Speno]

I'm working on adding SIA authentication support to OpenSSH for use on
Tru64 UNIX. The authentication bits are working but there's more work to be
done including checking for locked accounts and setting resource limits.

Anyway, most things seem to be working fine except for scp and I'm looking
for a little help. Here's some output:

% scp -v lopan:sl.tar .

I've got a working scp from ssh-1.2.27 around and that still works fine.

Any ideas?

Thanks.
