Range from String / String from Range problem

[Riccardo Mottola]

Hi,

on FreeBSD/Clang I noticed that ProjectCenter is not scrolling to the 
classes / methods parsed. Strange, since I extra fixed the parser! Also, 
on my Linux computer it works.

The code, in PCEditor, is fairly simple:

  classNameRange = NSMakeRange(0, 0);
  enumerator = [parserClasses objectEnumerator];
  while ((class = [enumerator nextObject]))
    {
      if ([[class objectForKey:@"ClassName"] isEqualToString:className])
    {
          NSLog(@"range string: %@",[class 
objectForKey:@"ClassNameRange"]);
      classNameRange =
        NSRangeFromString([class objectForKey:@"ClassNameRange"]);
      break;
    }
    }

  NSLog(@"classNameRange: %@", NSStringFromRange(classNameRange));

the range is re-created from they dictionary value which is a string. 
Perhaps it is not the most efficient way to put ranges in a Dictionary? 
In any case I suppose it should work. Here is the output of the two NSLogs:

2015-11-12 15:25:01.236 ProjectCenter[3684:100116] SCROLL to class: 
"@AppController"
2015-11-12 15:25:01.237 ProjectCenter[3684:100116] range string: 
{location=256, length=13}
2015-11-12 15:25:01.237 ProjectCenter[3684:100116] classNameRange: 
{location=34359738624, length=34359738381}

This means that the parser worked and that the value inside the 
dictionary is sane. However, once a String is re-extracted and 
re-printed, the value is havoc.
A breakpoint in the debugger doesn't work, strangely... I will 
investigate futher with a test program.
Do we have a testcase for this in base I can eventually extend?
