Debugging help with VS2008 MFC dll, VS2010 native XLL, and Interactive Brokers C++ Posix

:thumbsup:I've written Excel C API code for simple functions in VS2010.
I also using Interactive Brokers C++ Posix API, which I can compile in VS2008 and not VS2010.

I fill a data structure with a call to a VS2008 dll around Interactive Brokers C++ Posix API. If I pass in std::deque< std::deque<_variant_t> > it works fine from VS2008 exe. However, I get a run-time memory error from VS2010 dll that is also my XLL.

When I debug from my XLL code in Visual Studio 10.0, I get the error
("_Pdeque != 0 && ((_Mydeque *)_Pdeque)->Myoff <= _Off && _Off <= (((_MyDeque*)_Pdeque)->_Myoff+((_Mydeque*)_Pdeque)->_Mysize)", 0)
from deque file in Visual Studio 9.0.

Could this be an error related to different representations of std::deque or _variant_t in VS2008 MFC and native VS2010? Is there any way around this problem other than recreating my projects in Visual Studio 2008?

I also wanted to mention that I use a template class that utilizes .NET threads in CLR projects and native threads in native projects. This also could be related. I created a standalone Visual Studio 2008 XLL just for Interactive Brokers and it no longer crashes. However, the socket disconnects... I also changed my Excel C API usage to a macro instead of a function and turned off all of my user interface customization in the Excel C API code.

Any idea what the problem may be? My guess is a very intricate memory error... I do not think it is related to the template class since the definitions are all in header files and I haven't had problems using the class with different multi-threading techniques in different types of projects.
