[Insight-developers] Question about delete on VC++

[Miller, James V (Research)]

Strange.  If we were building Dlls, I would say that maybe we were
allocating nodes in one DLL and deallocating them in another DLL.
(I think each DLL has its own heap management). But since we are 
not building DLLs, then that is not the problem.

Have you run with VC the version that prints out all the node
allocation and deletions?

Is there anything "inside" a node that is not being deleted? Perhaps a 
subitem is missing a destructor that needs to do something that another
compiler is providing by default.
