[Vv] leaks

Tue Jun 15 22:28:28 CEST 2010

Hi David,

That's a good one!!!

There is not flag like this one in ITK... Theoretically, 
itk::SmartPointer should take care of releasing the memory of each 
instantiation of ITK class, but some leaks may occur within a class when 
memory is not properly deallocated. Then the only way is to use standard 
tool like valgrind or purify.

Bonne soiree,
Arnaud
