Updated to revision 402, still have the segfaulting problem.  Log file is at 
ftp://ftp.fomsystems.com/pub/log2.dat if anyone is interested.  As you can 
see from the log after connecting the telnet session I simply did a couple 
of 'mdw' commands just to see if the target was alive, then issued a 'flash 
probe 0' command.  There are 3 lines in the log after receiving this command 
and then *poof*.  I'll see if I can run this down but I'm sure someone here 
can probably figure it out first...
