I have a .EXE which depends on DLL A. The .EXE uses LoadLibrary to load DLL B, which also depends on DLL A. The LoadLibrary call on DLL B failes, reporting "invalid access to memory location" in its static initializer. The static initializer for DLL B is using static data from DLL A, and fails whether trying to assign to that static data or invoke a method which likely also modifies the static data.
This application is *not* using MFC or MFC shared libs.
How can I fix this? What's causing the memory fault?

Yes, both data and functions are exported from A.
Here's the static declaration, from DLL A:
namespace NS { vector<CORBA::Narrow_proto
Here's the access, from DLL B:
struct _global_init_MYPLUGIN_Deri
_global_init_MYPLUGIN_Deri
{
vector<CORBA::Narrow_proto
if( vec == NULL )
vec = ::NS::BasicType::_narrow_h
vec->push_back( MYPLUGIN::DerivedType::_na
}
} __global_init_MYPLUGIN_Der
Hard to say. Probably, the problem is as follows.
The .h file [may be] declares the static data differently for EXE (as imported) and DLL (as exported).
It is correct as long as you use this header in the EXE and in the DLL that exports the data (A).
But for B.DLL, the data must be declared as IMPORTED as well, but not as exported (the header file may detect that it is compiled in DLL mode and make the data exported).

So you export the data, not functions only, from the A?
Could you show the code related to the static data?
