Inclusion of itkImageFileReader.h creates the memory leaks, because it uses the singleton itkImageIOFactoryRegisterManager.h. Looking at the class, it does not have a destructor. By looking at the IO classes instantiated from there (such as itkMetaImageIOFactory.cxx), they seem to be designed to never be destructed thus always leaking some small amount of memory at the program termination. I know this is annoying for those who use leak detectors, but if am willing to bet that this issue was discussed and weighed against alternatives before being implemented.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Regards,</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Dženan</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 10, 2016 at 12:18 AM, Lee, Kyungmoo <span dir="ltr"><<a href="mailto:kyungmoo-lee@uiowa.edu" target="_blank">kyungmoo-lee@uiowa.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I am using MS Windows 7, MS Visual C++ 2015, ITK-4.9.0, and CMake 3.4.3. When I click [Test]-[ITK] in the menu in Debug, x64 mode, the example clashes in itkImageFileReader.hxx. Can you check my source code? Thanks a lot!</span><u></u><u></u></p>

<p>Hi Matt,<u></u><u></u></p>
<p> <u></u><u></u></p>
<p>Thank you for replying. I would like to use ITK in my MFC application. It has another memory-related problem in my application (See the following figure). I guess that there is a conflict between ITK smart pointer and MFC structure. If you fix InsightApplications-4.8.0/ItkMFC,
it would be a good reference for my MFC programming. Thank you so much!!!<u></u><u></u></p>

<p>Hi Kit,<u></u><u></u></p>
<p> <u></u><u></u></p>
<p>We are in the process of deprecating InsightApplications.<u></u><u></u></p>
<p> <u></u><u></u></p>
<p>However, if you create an MFC application that uses ITK, there should be no issues or memory leaks.<u></u><u></u></p>
