Do you have POSIX_BUILTINS set? It's needed to get the special
behaviour of not restoring the environment. I don't think that
behaviour changed recently, though.
% zsh -f
% setopt posixbuiltins
% FOO=bar export FOO
% printenv FOO
bar
%
and
% ARGV0=sh zsh -f
$ FOO=bar export FOO
$ printenv FOO
bar
$
I can believe there could be other weird interactions around, however.
