--- Comment #6 from Will <will at aether.com> ---
This is still broken on Mac OS X, preventing me from writing portable
scripts. Installed latest 6.6p1 and it's still broken, even though this
bug seems very old. Works fine on my Linux systems:

will at x ~$ which ssh
/usr/local/bin/ssh
will at x ~$ ssh -V
OpenSSH_6.6p1, OpenSSL 1.0.1h 5 Jun 2014
will at x ~$ ssh-keyscan -t rsa login.itd.umich.edu | ssh-keygen -l -f
/dev/stdin
# login.itd.umich.edu SSH-1.99-OpenSSH_5.2p1-hpn13v6
/dev/stdin is not a public key file.
will at x ~$ ssh-keygen -l -f <(ssh-keyscan -t rsa login.itd.umich.edu)
# login.itd.umich.edu SSH-1.99-OpenSSH_5.2p1-hpn13v6
/dev/fd/63 is not a public key file.

Temporary files are the only way on Mac.
