Summary	0002162: Memory leak, when using the module Tractography Fiducial Seeding
Description	To reproduce the memory leaks : 1/ Open Slicer, then load "DTI Volume" by the sample data 2/ Add a fiducial 3/ Open "Tractography Fiducial Seeding" module 4/ Close Slicer the "py_NeurosurgicalPlanningTutorial" test is failing due to those leaks !

jcfr 2012-06-28 13:20 administrator ~0004981	Fixed in r20516 See http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=20516 I would really really really recommend using Smart pointers ! It just makes the management of memory painless.
