[Insight-users] itk::ObjectFactoryBase::RegisterFactory under win32

[Neil.Burdett at csiro.au]

Hi,
     I'm currently porting an application from Linux (Ubuntu) to Windows (Visual Studio 9 2008). The code works fine under Linux but the following line in Visual studio

  itk::ObjectFactoryBase::RegisterFactory( itk::INRImageIOFactory::New() );


causes a memory leak (shown by the visual leak detector):

---------- Block 46358 at 0x04EBACB8: 92 bytes ----------
  Call Stack:
    f:\dd\vctools\crt_bld\self_x86\crt\src\dbgmalloc.c (56): malloc
    f:\dd\vctools\crt_bld\self_x86\crt\src\newaop.cpp (7): operator new[]
    c:\milxview-win32-depend\src-itk-3.16.0\code\common\itklightobject.cxx (102): itk::LightObject::operator new
    c:\milx-view\lib\include\itk-ext\modules\io\itkinrimageiofactory.h (52): itk::INRImageIOFactory::New

    0x7C817077 (File and line number not available): RegisterWaitForInputIdle


Under windows do we have to delete this object? Because I see there is a win32 branch in the itklightobject.cxx i.e.

/**
 * Avoid DLL boundary problems.
 */
#ifdef _WIN32
void*
LightObject
::operator new(size_t n)
{
  return new char[n];       <--- This line corresponds to line 102 above
}

void*
LightObject
::operator new[](size_t n)
{
  return new char[n];
}

void
LightObject
::operator delete(void* m)
{
  delete [] (char*)m;
}

void
LightObject
::operator delete[](void* m, size_t)
{
  delete [] (char*)m;
}
#endif

Any help most appreciated

Neil
