Dovecot v2.2.25 crashed on startup in Mac OSX

[Michael Chen]

I built from dovecot-2.2.25.tar.gz on Mac OSX 10.11.15 (El Capitan) the
usual way:

    CFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure
    make
    sudo make install
    sudo /usr/local/sbin/dovecot

It consistently crash on startup with the following entries in
/var/log/mail.log (edited backtrace):

It looks similar to this report:

HomeBrew installed 2.2.24, and it works in my Mac. Can someone confirm this
is a bug?

I also built 2.2.25 with debug, but can't make it break at line
iolook-kqueue.c:67

    i_panic("kevent(EV_ADD, READ, %d) failed: %m", io->fd);

Thanks
