Funny, as I went to sleep last night I thought of just that solution. 
In practice, though, while it doesn't hang, it doesn't give the correct 
answer either.   As Corinna said, the malloc override needs to be 
functional, in that it allocates memory which can then be free()d.  So 
this isn't going to be quite so simple. :-(
