modelProbeMap in simpleExperSwarm.m

[Zafar Iqbal]

in Swarm-1.1 tutorial simpleExperSwarm the modelProbeMap 
object is created but not displayed. The relevant code is :-
if (numModelsRun == 0)
    {
      // Build a customized probe map for the class ModelSwarm
      modelProbeMap = [EmptyProbeMap createBegin: self];
      [modelProbeMap setProbedClass: [modelSwarm class]];
      modelProbeMap = [modelProbeMap createEnd];
      
      // Add in a bunch of variables, one per simulation parameter
      [modelProbeMap addProbe: [probeLibrary getProbeForVariable: "worldXSize"
                                             inClass: [modelSwarm class]]];
      [modelProbeMap addProbe: [probeLibrary getProbeForVariable: "worldYSize"
                                             inClass: [modelSwarm class]]];
      [modelProbeMap addProbe: [probeLibrary getProbeForVariable: "agentDensity"
                                             inClass: [modelSwarm class]]];
      // Now install our custom probeMap into the probeLibrary.
      
      [probeLibrary setProbeMap: modelProbeMap For: [modelSwarm class]];

    } 

----end of code-----

I added the the line:
CREATE_ARCHIVED_PROBE_DISPLAY (modelSwarm);

This produces a display but when the model is dropped for 
the next iteration, I get a "bus error" or "segmentation 
fault".
I tried to drop the probe using:
[modelProbeMap drop];

This had no effect. 
Is there a way of displaying the modelProbeMap without 
errors?

I'm using sparc-sun-solaris 2.5.1,  Swarm-1.1
