FreeBSD jchurch.neville-neil.com 4.5-STABLE FreeBSD 4.5-STABLE #3: Sun Mar 17 23:00:31 PST 2002     gnn@jchurch.neville-neil.com:/usr/local/src-STABLE/src/sys/compile/JCHURCH  i386

>Description:
After I have started xdm and X11 (XFree86 4.2) on my machine
I can no longer get information on LOCAL (i.e. UNIX) domain sockets because
netstat seg faults.  I have built a version with debugging and traced this down to
the printf() call on line 149 of unix.c in -STABLE (the same line occurs in -CURRENT).
It would seem that the xsocket data structure passed to printf causes it to
barf.

>How-To-Repeat:
Run XFree86 4.2
Run netstat by itself
See sparks fly.
