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

[kent williams]

If you can send me a link to one of the image series that is causing the
memory leaks I can run it under valgrind and try and see what¹s leaking.

How are you diagnosing the memory leaks? Any idea where in the code they¹re
happening?
