On Windows NT 4.0 and Solaris 2.7, I don't get a crash.  I'm using
the current sources, though.  Although I can't think of a recent

Segmentation faults occur when you attempt to use a invalid memory.
For example, if you use a pointer that has been dropped.

You'll want to drop the selfConfig block...

- (void)drop
{
  [[self getZone] free: selfConfig];
  [super drop];
}
