Comment:

 This was actually segfaulting on me rather than giving me a bus error. I
 added a patch that will raise an exception saying that the 'array is not
 writetable' in a similar manner to exceptions raised by other forms of
 trying to set an element in a read-only memmapped array. I also took out
 an extra space in one of the others exception messages nearby.
