/* Test use of -awakeAfterUsingCoder:

This is a rather complicated, strenuous test, borrowing elements

from the fref.m test. */

/* Beginning of some parameters to vary. */

/* 0 and 0 works.
|

1 and 0 works for the first test, but has no way of getting the
|
||||
super_foo in second test right, because we haven't resolved the
|
||||
forward reference when -awakeAfterUsingCoder is called; this is
|
||||
an inherent problem of decoding.

0 and 1 crashes, as does NeXT's (for reasons related to forward

references, having nothing to do with awakeAfterUsingCoder). */
