BUG: Msvcrt.dll Does Not Initialize Global Objects

• Microsoft Windows CE Toolkit for Visual C++ 6.0
• Microsoft Windows CE Embedded Toolkit for Visual C++ 5.0
• Microsoft Windows CE Platform Builder, version 2.11

SYMPTOMS

When targeting Windows CE 2.00 and linking with C run-time dynamic libraries (Msvcrt.dll or Msvcrtd.dll), global C++ objects are not initialized.

RESOLUTION

If C++ global objects are being used, do not use the C run-time dynamic libraries. Use the static run-time libraries instead.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

The C run-time dynamic libraries were available only with Windows CE version 2.0. Devices using Windows CE version 1.0 or Windows CE 2.01 and later should not use these libraries. The following program demonstrates the problem when linked with Msvcrt or Msvcrtd:

   // Sample.cpp -
   // 
   // Should show the constructor message before the main program
   // message. Instead, the constructor message isn't shown at all.
   // 

   #include <windows.h>

   #define MSG(z) MessageBox(0,z,TEXT("Sample"),MB_OK)

   struct MYCLASS
   {
      MYCLASS()   { MSG(TEXT("Constructor called.")); }
   };

   MYCLASS myclass;

   int WINAPI WinMain(

      HINSTANCE   hInstance,
      HINSTANCE   hPrevInstance,
      LPTSTR      lpCmdLine,
      int         nCmdShow)
   {
      MSG(TEXT("Main program."));
      return 0;
   }
