It's a bug that crept in that means the stub DLLs do not properly export
their symbols. It's fixed in the CVS version of omniORB. Or you can get
the latest snapshot from here:

It's the joy of Windows. If you get DLL linkage wrong, everything looks
like it's working, but all the pointers are bogus. Really helpful, that.
