[Boost-users] Windows: Mixed .NET and native C++ with Boost

Hi all,

I try the following scenario:

- a C++ library (my own code), unmanaged, makes use of boost (e.g. regex)
- a C++ .NET application (windows forms based) planned as GUI (having used Borland C++ builder in the past, the windows forms approach looks quite appealing to me)
- my C++ library header is included in the .Net form header file wrapped in a #pragma unmanaged/managed pair.

I compiles and links well.

For simple test purposes, I instantiate a class from my C++ library in the form constructor. Calling some unmanaged code from my library there creates a debug assertion:

"Debug Assertion Failed!
[...]
Expression: _CrtIsValidHeapPointer(pUserData)
"

The call stack at that moment is as follows ("Application.exe" is my Windows Forms Application):

To me, it looks like the DLL initialization failed.

Is anybody out there who might help me with this issue? I am completely new to this .Net thing...

Best regards
Matthias
