>Description:
The Scilab port works Ok on 6.2-stable and xorg 7.2.
Starting Scilab 4.1.1 in 7.0-current SMP exits.  Debug reveals a
corrupt stack.  This looks similar to another panic reported on the
mailing list which reports a corrupt stack.
	
>How-To-Repeat:
In 7.0-current, run scilab.
# scilab -debug
