Hi,

This started to happen after updating to a recent 7-current
about one week ago (it was working fine with a previous 7-
current that was a few weeks older).  The shell is zsh.

zsh$ /usr/bin/su
/libexec/ld-elf.so.1: environment corrupt; missing value for
zsh$ 

So su(1) fails to start.  Interestingly, when I first start
an sh shell, I still get the same error message, but the
shell starts anyway.  Then I can use su(1) without problems:

zsh$ sh
sh: environment corrupt; missing value for
$ /usr/bin/su
Password:

It was my impression that there should be more printed in
the error message after "missing value for", so I made a
hexdump:

6e 67 20 76 61 6c 75 65  20 66 6f 72 20 1b 5b 34  |ng value for .[4|
7e 0a                                             |~.|

Sure enough, my environment _does_ seem to be corrupt
when I look at the output of env(1):  There are several
empty lines and some lines with random garbage characters
and control characters.  However, after starting sh,
the garbage is gone.  So sh seems to "repair" it somehow.

Is this a bug in -current's environment handling?  Or is
it a bug in zsh that has only been triggered by recent
changes in FreeBSD -current?

Note that I use exactly the same zsh version and exactly
the same zsh start profiles (i.e. basically the same
environment contents) on a large number of machines,
FreeBSD and other, and this problem _only_ exists on
a recent FreeBSD 7-current.

Best regards
   Oliver
