Hello.

I have a trouble about difference between Release and Debug version 
on Windows. 
I want to use QPixmap in exported function of DLL(Dynamic link library). 
Exporting has no problem. But following function, Handle is valid 
in a version compiled on Debug in VisualStudio2005. But Handle is NULL 
in compliled Release. Then it causes critical error in QPixmap 
constructor on Release version. How should I do to let 
QCoreApplication::instance () derive to DLL? 
Best regards


extern "C"{
__declspec(dllexport) QIcon *DLL_GetIcon(void);
};

__declspec(dllexport) QIcon *DLL_GetIcon(void)
{
  QCoreApplication *Handle=QCoreApplication::instance (); //For test

  QPixmap  D(":Resources/Panel.png");
  return(new QIcon(D));
}


My environment:
IDE      : VisualStudio2005
Compiler : Intel compiler 10.0.27
Qt       : 4.3.2
OS       : WindowsXP 64bit edition
