it is rather surprising that you didn't see this crash with another compiler 
before. The problem is clearly in this frame:
  #4  0x0804c4bf in +[Clock initialize] () at Clock.m:53
The statement at that line is
        dayWeek = [NSArray 
arrayWithObjects:@"su",@"mo",@"tu",@"we",@"th",@"fr",@"sa"];
The argument list lacks the nil sentinel to indicate where the list of objects 
ends.
