Slackware 14.2 64bit . In my case just using both of
SET CPU MODEL=VAXStation
SET GVSS ENABLE
Which causes the Segfault . Either one seperately there is no SegFault
and most every but 'boot cpu' works . But that is another story . Which I have
not had time to diagnose as of now . Will try strace of running process and see
what happens .
