[prog] This segmetation fault makes no sence to me.

[Sue Stones]

Well I soved my loader error eventually, but now I have a segnemtation fault 
and I have no idea what it might be causing it.   I think of segmentation 
faults as trying to access some address that the program has no rights to.  
But in this case  the fault occurs when it has fininished doing anything.  I 
will copy the relevent functions below with the output.

As far as I understand it is not until after smith has been added and 
everything initialised, and when things are falling back out of the end of 
functions that the segementation fault occurs.

Can anyone shed any light on this?
