Hi list,

I just found that an invalid property-condition causes Chicken to segfault:
(abort (make-property-condition 'exn 'location "string"
                                     'message "error"
                                     'arguments '()))

The reason is that location needs to be a symbol, not a string.  Of
course, a type check would be in order here :)
