Hello and thanks for the advice. I tried to enable the "/clr" flag for
my native GCPS library, but then I just get a bunch of complaints that
the compiler cannot compile my C source files with the /clr option.

Hello Ben. I tried to download Visual C++ 2008 Express Edition today.
However, it is not usable to compile my project because I use the MFC
library and apparently this is not included in the expression edition of
VC++ 2008.

I think this indicates that not all your source files are using the same
runtime library settings (i.e. /MT and whatever the equivalent is for "Use
MFC in a Shared Library").

I managed to make this link error go away by checking out the code again
from Subversion and compiling and linking everything from scratch.

However, I still get the same crash in GcpsDotNetApi.dll!`dynamic
initializer for 'afxModuleState''() Line 66 + 0x14 bytes

It appears that this is caused by the use of the MFC library in the .NET
component GcpsDotNetApi.dll. I think the variable afxModuleState is
defined somewhere in the afx header files.

I read about initialization of mixed assemblies here:
http://msdn.microsoft.com/nb-no/ms173266(en-us).aspx

I think my problem might be some kind of "loader lock issue" , but I
have no idea how to fix it, since I did not declare the afxModuleState
variable myself, and hence I cannot put e.g. #pragma unmanaged on it.

I have been trying for many days now to solve the problem but still no
success. I found this Microsoft article describing a somewhat similar
problem:
http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=99715

I have tried to replace the main subroutine with CWinApp::InitInstance()
in my main application and changing the entry point from main to
WinMainCRTStartup but I still get the same crash. (I guess I would have
to change something in GcpsDotNetApi.dll and not in my main application
to get rid of this problem).

Do you have any further ideas on what might be wrong? Do you know of any
support e-mail addresses or newsgroups that would put me in direct
contact with people from the Visual C++ team in Microsoft regarding this
problem?

I think that to get better help you may try to provide a reproducible
minimal example.
(e.g. a VS2008 solution download with minimal source code, which reproduces
the crash.)
