<br>Hi Michael,<br><br>Thanks for reducing the problem to a minimal<br>example and posting it to the list.<br><br>I have build your code under Linux (Ubuntu)<br>and ran Valgrind on it.<br><br>Found that you were not initializing the pixel<br>

<br>was replaced with:<br><br> TransformType::ConstPointer cversor = iversor.GetPointer();<br><br><br>although a better solution is to change the API of<br>your "transformImage" method to take const raw<br>pointers instead of SmartPointer. (the code was<br>
modified accordingly).<br><br>The code runs under Linux, both under Release and<br>Debug without crashing.<br><br>Please find the modified code attached.<br><br>(Note that, I put the boolean flag of the import filter<br>to "true", temporarily, in order to avoid a memory<br>

<br>
I checked your points 1) and 3) to 5) but had no luck.<br>
<br>
But with 2) i have tracked down the problem to be an interplay of ITK and wxWidgets and found a workaround too.<br>
Basically, when i use an wxSplitterWindow ITK crashes, when commenting the wxSlitterWindow stuff out ITK works as expected. I used ITK 3.14, wxPack 2.8.9 and Visual Studio 2008 Express Edition.<br>
I have created a minimal example application (main.cpp, CMakeLists.txt) attched at the end of the message that makes this problem reproducable without additional dependencies. Running in Release or RelWithDebInfo will crash under Windows XP at resampler->Update(). Commenting out line 36 (m_splitter2 = new wxSplitterWindow( this, wxID_ANY, wxDefaultPosition, wxDefaultSize, 0 );) will make ITK running smooth without a crash.<br>
<br>
And, a workaround was found while trying program on an other PC. By using wxPack 2.8.8 instead of wxPack 2.8.9 the problem is gone. So, a downgrade to prior minor Version of wxWidgets is sufficient.<br>
<br>
But, i have not really an exmplaination for that. Especially the fact that the splitter in not instanciated before ITK runs. Would be nice to find how wxWidgets influences ITK!<br>
<br>
Best reguards,<br>
