[ITK-users] [ITK] Buffered Region out of Range error

We also ran an experiment where we moved the ITK Dependency from just the plugin down into one of our lower level libraries. So now we have the plugin dependent on a lower level library which then is dependent on the ITK Libraries. Now the code seems to execute and produce results. This was on OS X 10.9 and 10.10. So it seems that there is some odd issue with loading the ITK libraries through a plugin mechanism? Does ITK need the “-fPIC” added to the list of compile commands?
Qt is actually built WITHOUT C++11 support but still links against libc++. They (the Qt Devs) set the OS X Min Deployment Version to 10.7. I have no idea what that triggers or not.
Thoughts?

Where-as on OS X 10.9 and 10.10 they are all linked against libc++. So I am thinking, at least for ITK 4.7.2 we have stumbled upon an issue with the C++ library? We are now recompiling ITK using the USE_COMPIILER_HIDDEN_VISIBILITY=OFF as you have suggested and will report back those findings.

Things like dynamic_cast can fail, along with specific exception types not being caught. We have recently improved the export specification in ITK, and you should upgrade. This may be a larger architectural problem, and techniques like explicit instantiation of object which can be shared can help.

It does this by provided a full export specified interface free from templates, and explicitly instantiating many parts of ITK.

We are trying to integrate ITK into our project DREAM.3D (github.com/dream3d) which uses a plugin system to load user developed data analysis filters. The failure mode we are seeing is when 2 filters, in different plugins, use the same ITK code. The DREAM.3D plugin that contains the DREAM.3D Filter that gets loaded first will run through without issues. The second DREAM.3D Plugin that contains the second DREAM.3D Filter will fail with the exception message. The ITK code is exactly the same except for the name of the c++ class that holds the code. We have replicated this on OS X 10.9 and 10.10. We can NOT replicate the issue on Windows (VS2013) or Linux (Clang 3.6). We have it down to a fairly simple DREAM.3D test case but not an ITK test case. After moving some codes around and moving some of our looping code inside the “try-catch” block we finally started seeing the exception messages. I am hoping we are just using ITK incorrectly and OS X is just exposing the incorrect use. The weird part is that we get the correct results on the other systems so it is not like the other platforms have a silent failure.
