"su root -c /path/to/zsh" runs the shell.  When I exit, I get

    zsh: suspended (tty output)  su root -c /path/to/zsh

which is confirmed by jobs.  If I foreground the job, it finally exits
properly.  This is if both the user and the root shell are 4.1.1 without
the patch.

If the root shell is patched, then this problem doesn't happen (doesn't
matter what the user shell is).

If the user shell is patched but the root shell is not, then I get the
I/O error I described before.

Indeed.  I'll recompile both the patched version and the unpatched
version from scratch and see if I can reproduce all this behavior.

Thanks,
