[Insight-users] Memory leak in the class "vnl_sparse_lu" and its solution

[Xavier Mellado Esteban]

    Hi,

    I found a memory leak in the class "vnl_sparse_lu" located under  
the "./Utilities/vxl/core/vnl/algo" folder in ITK 3.20.

    The constructor function allocates memory that it is never freed,  
and the destructor function should be modified. This bug is fixed in  
the latest release of VXL (1.14) (maybe in previous releases, but I  
only checked the last one).

    The files vnl_sparse_lu.h and vnl_sparse_lu.cxx of VXL 1.14 only  
differ from the ITK ones in this point, so they can be directly  
replaced to solve the problem.

            Best regards,
                            Xavi
