freebsd stable - Apr 2008 - File descriptor passing broken in FreeBSD 7?

Hi,

I recently tried to use the newly released mod_rails  
(www.modrails.com) for Apache, and discovered it doesn't work on  
FreeBSD 7.  It does however work on FreeBSD 6 just fine.

I tracked it down to sendmsg() as detailed here:

	http://code.google.com/p/phusion-passenger/issues/detail?id=16

The mod_rails/passenger unit tests fail on FD passing, as do the Ruby  
1.8.6 standard unit tests. They all fail with EBADF

I've also tried this test case (with minor appropriate changes to file  
paths etc.)

	http://www.gnome.org/~markmc/code/test-descriptor-passing.c

Again it works in FreeBSD 6, but not in FreeBSD 7 (albeit with  
ECONNREFUSED not EBADF).


Any ideas?

Cheers

Phil

Works fine on 7.0-STABLE from end of last week (i.e., doesn't core-dump, and
outputs the contents of test-descriptor-passing.c, to which I adapted the 
filename).

uname -a:

FreeBSD phoenix.modelnine.org 7.0-STABLE FreeBSD 7.0-STABLE #2: Fri Apr 11 
13:46:16 CEST 2008     root@phoenix.modelnine.org:/usr/obj/usr/src/sys/HEIKO  
i386

I ran the program as an unprivileged user.
