[Insight-developers] Memory leaks after reading some dicom files

[Massimo Esposito]

I used the sofware GlowCode to detect memory leaks and this is the report it
generated.
In attach there is this report.
I execute my application in debug mode using Visual Studio .Net 2003. So
when i close the application the memory leaks are printed and iI have a
report like the one obtained using GlowCode .
I hope the file attached can be useful to you.
