[syslog-ng]killed by HUP signal on Mac OS X 10.3

[Jeremy Mates]

The syslog-ng daemon dies on Mac OS X when a HUP signal is sent:

$ sudo /usr/local/sbin/syslog-ng -d
io.c: Preparing fd 4 for reading
io.c: Preparing fd 5 for reading
syslog-ng version 1.6.2 starting
io.c: Preparing fd 7 for writing
io.c: Preparing fd 8 for writing
SIGHUP received, restarting syslog-ng
poll.c:282: failed assertion `pArray != (struct pollfd *) NULL'
zsh: abort      sudo /usr/local/sbin/syslog-ng -d

Software versions involved:

syslog-ng 1.6.2
libol 0.3.13
gcc 3.3 20030304 (Apple Computer, Inc. build 1495)
Mac OS X 10.3.3 (build 7F44)
