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

[Neil.Burdett at csiro.au]

Hi Luis,
            in this particular case the

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

line is being called from an executable not a DLL as it's a unit test case

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 ----------

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
