Right. Did you play games with the index when you malloc'd 9?

man malloc

The  malloc()  function  allocates size bytes and returns a pointer to the 
allocated memory.  The memory is not initialized.  If size is 0, then  
malloc()  returns  either  NULL,  or  a  unique pointer value that can 
later be successfully passed to free().

'The memory is not initialized.'  is underlined on the man page. Some days 
you get lucky.
