X11 crash on NetBSD 1.4

[Andrea <andrea.franceschini%linet.it@localhost>]

Hi!

After the upgrade to NetBSD 1.4 i experimented funny crashes on X11:(

It seems to work fine for after a while it crash.

I also used the patched Xamiga server ,but still there's something wrong.

Using standard twm all work pretty fine,nearly every programs i tried works 
without hangs
But if i tries running WindowMaker i got a crash:

This is my config

.xserverrc

X -dev /dev/grf0 -W 640 -H 512 -D 8 :0

.xinitrc

#!/bin/sh
# $XConsortium: xinitrc.cpp,v 1.4 91/08/22 11:41:34 rws Exp $

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/usr/X11R6/lib/X11/xinit/.Xresources
sysmodmap=/usr/X11R6/lib/X11/xinit/.Xmodmap

# merge in defaults and keymaps

if [ -f $sysresources ]; then
    xrdb -merge $sysresources
fi

if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi

if [ -f $userresources ]; then
    xrdb -merge $userresources
fi

if [ -f $usermodmap ]; then
    xmodmap $usermodmap
fi

# start some nice programs

#twm &
wmaker

I tried using gdb on core dump.

#gdb Xamiga Xamiga.core

Sometimes using xdm i also got a xsm.core.
