    PR libobjc/18764
    * class.c (__objc_add_class_to_hash): Return YES if the class was
    added, and NO if it already existed.
    * init.c (__objc_init_class): If __objc_add_class_to_hash returns
    NO, then abort the program with an error message.
    * objc-private/runtime.h (__objc_add_class_to_hash): Updated
    declaration.
