hashtable-based objects: minimum fixups.
Calling hashtable_index from find_object before objs is created would result in division by zero failure. Avoid it. Also the given object name may not be aligned suitably for unsigned int; avoid dereferencing casted pointer. Signed-off-by: Junio C Hamano <junkio@cox.net>
