Object reference not set to an instance of an object

Another question:

I have a mixed managed/unmanaged MVC++ 2003 project and it uses a VC++ 6.0
lib file that only uses windows functionality no MFC. So far it worked fine.

But somehow now I get a an error during the construction of a pure unmanaged
class at the very beginning,

An unhandled exception of type 'System.NullReferenceException' occurred in
Three.dll
Additional information: Object reference not set to an instance of an
object.

The function:

public: CPluginExt(DWORD style, LPCTSTR lpszName, LPCTSTR lpszDescription,
LPCTSTR lpszStdOut, LPCTSTR pszStdErr ) :
CPlugIn(style,lpszName, lpszDescription, lpszStdOut,
pszStdErr ) {
Init();
};

The debugger stops on that very first line of the constructor, at that point
I did not execute functionality.

The odd thing is that if I recompile the lib file with VC++ 2003 then it
works.
But plans here is that they only want to distribute the VC 6.0 lib file and
not many versions for every compiler.

Any ideas?
 
Static libs in general are specific to a version of the compiler. Third
party vendors need to provide different versions.

That I was afraid of, thanks.
