--- Comment #1 from Colin Watson <cjwatson@debian.org> ---
This bug is referenced in the changelog for OpenSSH 9.1/9.1p1 as being
fixed in that release:

* ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config
are now first-match-wins to match other directives. Previously
if an environment variable was multiply specified the last set
value would have been used. bz3438

Should it be closed?

I've just verified this with Colin's fresh openssh-client 1:9.1p1-1:

When set in ssh_config as:
SetEnv LC_ALL=C
SetEnv LC_ALL=C.UTF-8

one now gets:
setenv LC_ALL=C
in -G and in -v:
debug1: channel 0: setting env LC_ALL = "C"

And without the following in the config:
SetEnv LC_ALL=C LC_ALL=C.UTF-8
one now gets:
setenv LC_ALL=C
in -G and in -v:
debug1: channel 0: setting env LC_ALL = "C"

So I can confirm it's been fixed.

I'll leave it open for now, cause maybe ssh upstream wants to add some
documentation?

Cheers,
Chris.
