How did you configure and compile this?  That particular problem should
have been caught by this change to configure prior to 8.9:

    Extend select+rlimit sanbox test to include poll.

    POSIX specifies that poll() shall fail if "nfds argument is greater
    than {OPEN_MAX}".  The setrlimit sandbox sets this to effectively
    so this causes poll() to fail in the preauth privsep process.

    This is likely the underlying cause for the previously observed
    behaviour of select() on plaforms where it is implement in
userspace on
    top of poll().
