Note the underscore.
Nevertheless the debugger seems confused. The self argument of the -addObject: method, which should be the leftLineRangesArray, is 0x4817058 while debugger says leftLineRangesArray is (class NSMutableArray *) 0x184b9849. This sort of thing usually happens when optimization is turned on. But anyway, given this discrepancy there's no alternative to Adam's advice: single-step through the program, probably from the start of DiffWrapper -initWithFilename:andFilename:.
