Hello again,
I just stumbled upon a little bug in ETGetSuperclass() (from
NSObject+Etoile.m). If you were trying to resolve the superclass of a
root class, objc_lookup_class() would be called with NULL as an
argument, resulting in a crash. In the attached patch this is fixed for
the GNU runtime. I'm not sure if other runtimes need similar treatment.
Cheers,
Niels
