Thread: Losing reference between dlls

Hi guys. I've got a weird situation that I don't know how to handle. You see, I'm using a few dinamically linked libraries and I don't know why but the memory reference for a variable in another dll was lost. And it caused an unhandled exception. To illustrate my problem, I'll try to write a short version of it.

Consider I have this class in my main program (MyApp.exe):

Code:

MyDllClass1 gMyDll1;

class MyApp
{


   public:
...
      void create();

}

//Method definition
void MyApp::create()
{
...
      gMyDll1 = new MyDll();
      gMyDll1->create(); //exception here. it calls the methods that is defined inside a dll called MyDll.dll
...
}

When I debugged it and traced it inside the MyApp::create(), I found that mMyDll1 was initialized correctly. But when I traced into MyDll::create(), I found out that the this pointer of gMyDll1 object was null (thus the exception). How can this possible? I'm quite sure that the mMyDll1 wasn't deleted.

Can anybody help me here? Thanks a lot in advance.
