This simulation probably has a collection that gets nil assigned to dead 
or empty objects.   The easiest workaround is to find all the places 
`step' is called and ensure that before that message is sent that it 
checks to see if the object is not nil.    E.g.

if (obj == nil)
 printf ("attempted step message to nil");
else
 [obj step];
