I tried with Mac version (build 2012-09-12) and there was only a signal-slot problem:

Object::disconnect: No such slot qMRMLSceneModel::onDeviceVisibilityModified(vtkObject*)

The reported crash might be Windows-specific. I will check later.

On Windows in debug mode I get the following message in an error pop-up dialog:

Debug Assertion Failed!
Program: ...SlicerApp-real.exe
File: c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\list
Line: 242

Expression: list iterator not incrementable

After that if I press Ignore, I get the following in a similar window:
Expression: ("Standard C++ Libraries Out of Range", 0)

After these two exceptions, Slicer crashes with the following call stack:

I'm still not sure why this happens, but changed destructor process to avoid UnregisterMessageConverter() call.

I also found that the destructor of vtkMRMLIGTConnector was not properly called, when a connector node is removed from the scene. The logic class didn't unregister the connector node when it is removed from the scene, and the reference counter could not become 0. (This might not be related to the issue.)

I built Slicer from scratch this morning. I have the same problems:

1. Exception: list iterator not incrementable
2. Exception: ("Standard C++ Libraries Out of Range", 0)
3. Crash with a stack starting like this:

Thank you for your report.

Did you build with the latest version of the module? The change is within the OpenIGTLinkIF repository and Slicer cmake file is still pointing the old revision of OpenIGTLink... could you confirm that you tried after manually updating the module to the latest revision (revision 8015)?

I didn't update the module manually when I reported the error.

Now, I ran svn update on OpenIGTLinkIF and recompiled that module. The crash on close is gone, so this problem seems to be solved.
But I tested the connection by running TrackingServer from the OpenIGTLink package, and tried to receive it in Slicer with a client. I didn't receive any transform messages, however the transforms were printed on the server side. Could you too check if there is such a regression before updating the revision in Slicer cmake?

Thanks.

And a less related think is that vtk debugger reports that one vtkCommand object is not deleted when closing the program. If you happen to catch it while looking into the above problem of not receiving data as a client...

Status turns ON from WAIT, but no transform node is created.

Message converters (vtkIGTLToMRML* class) were not properly registered. I fixed the issue and it's working on Mac OS X. The OpenIGTLinkIF revision number is 8016.

The vtkCommand object issue has not been fixed yet.

I fix the vtkCommand object issue. The OpenIGTLinkIF revision number is 8017.

It looks fixed on Windows too. I don't get any exceptions or crash when closing slicer with connector nodes.
When will this be effective in the nightly Slicer build?
