I can't reproduce this. The key is that redir11.sub inherits file
descriptor 3 as an fd open for read on /etc/passwd, and echo gets a
write error when trying to write to it. This might also be affected
by SHELLOPTS setting posix mode, but I can't reproduce it even when
setting SHELLOPTS=posix in the environment.
It's also hard to see why starting bash without SHELL in the environment
sould make such a difference, since bash sets SHELL to the current user's
login shell, as found via getpwent.
