That static lib is probably the problem. Are you using the static library 
merely as a convenience to build things in steps, then you link everything 
into one big binary?

Or are you using the static lib in multiple plugins? If it's the latter case, 
you've violated ODR. Use a dynamic lib.

Remember the rule for plugins. A plugin system is composed of:
 a) zero or more applications
 b) zero or more plugins
 c) exactly one shared library / DLL, which all plugins and applications link 

The abstract base class must live in that library.
