/* airtest.c: AMBIGUOUS INTERIOR REFERENCE TEST

*
|
|
* This test case creates a bunch of string objects, registers them
|
|
* for finalization, and then discards the base pointers to those
|
|
* objects, keeping only ambiguous interior references.
|
|
*
|
|
* If any of these objects are finalized, then this means that the
|
|
* ambiguous interior references has failed to keep the object alive.
