A DLL that is using the Active Template Library (ATL) CImage class may cause a deadlock when it is unloaded from a process or when the loading process shuts down.

This problem occurs because the CImage class initializes and then shuts down GDI+ by using the static nested class CInitGDIPlus. This class initializes GDI+ before any CImage function that requires GDI+ is called. GDI+ is shut down by calling GdiplusShutdown when the CInitGDIPlus class is destructed. CInitGDIPlus is a static class that is destructed in a DLL in the context of DllMain. The documentation states that you cannot call GdiplusShutdown in DllMain.
