[Insight-developers] ITK Shared Build with VS2012

[Bradley Lowekamp]

Hello,

Are you using a CMake file to build your project?

Can you boil down this issue to a minimal example to reproduce this error?

What seems odd to me is that it sounds like osg92-osgDB.dll is export the std::basic_ifstream. So this may not even be an ITK issue.
