segmentation fault(s) after upgrading to CURRENT

Hi All,

I'm new to the list, so please be gentle :)

I have just upgraded from FreeBSD_6 STABLE to FreeBSD_7 CURRENT (about
time I did some testing / early adoption I thought).

[12:49]chrisp_at_valhalla ~ % uname -a
FreeBSD valhalla.systems.hq.inty.net 7.0-CURRENT FreeBSD 7.0-CURRENT #1:
Thu Oct  5 09:38:09 BST 2006    
chrisp_at_valhalla.systems.hq.inty.net:/usr/obj/usr/src/sys/VALHALLA  i386

My 'VALHALLA' kernel is a copy of 'GENERIC', but with
RAID/SCSI/FIREWIRE/ISA_NICs removed.

I have completed the upgrade but now I see many of the programs I run, are
core dumping...

This is from /var/log/messages: -

Oct  5 11:26:26 valhalla kernel: pid 805 (gdm-binary), uid 0: exited on
signal 11 (core dumped)

signal 11 (core dumped)
Oct  5 11:26:36 valhalla kernel: pid 1039 (gdnc), uid 0: exited on signal
11 (core dumped)

I've read the mailarchive and added 'compat5x_enable="YES"' to
/etc/rc.conf (I think that's what I should have done and the warning has
gone away now).

As for the Segmentation faults, what should I do to get myself back on track?

I an eager to do whatever it takes, to help diagnose and fix what's wrong.

Kindest Regards,
