Follow-up Comment #4, bug #24784 (project gnustep):

The exception reports the class as being an NSCalendarDate instance, not an
NSDate instance, so it's not that the message is going to the wrong class, but
the class has no implementation of the method ... however the class does
implement the method, so it must be a problem with the dispatch table causing
the method lookup to fail, which certainly sounds like an objc runtime error.

My guess is that it's like bug #20163 which is due to the runtime allowing
one thread to execute methods of a class while another thread is still calling
+initialize

I thought I'd reported that one on the gcc bug tracker, but I can't find it.
