[syslog-ng] syslog-n 1.6.8 crash and backtrace on FreeBSD 4.10

[Steve Shorter]

Howdy!

	I want to setup syslog-ng on a large server farm and
set up a test system on FreeBSD 4.10. The syslog-ng package from
the ports collection would crash... so I got the latest
sources of libio and syslog-ng and built it. It still
crashes and dumps core. Here is a backtrace.

	Looks like the  libio call io_iter does an assert() in line 283
and it kills/abort's the process

	Any more info required? I can test patches if you like.
	
	Ideas?


	thanx - steve


	The config file is simple like this
