[Insight-users] memory leak check in ITK?

Hi, Luis:
OUTPUT_MEM_BORROW means that the caller function will borrow image memory
from ITK image class and is responsible to release it. It is not used in my
code because the caller is a C function.
I commented out the suspicious code and re-run valgrind. I have similiar
results. Then I run example ResampleImageFilter2. I have similiar memory
leak too. One difference is that the leak size is 16. I guess it is due to
image dimension difference.
What do you think about the other 16 bytes leak? Seems that it is not
related to either ITK or my code. Just normal c++ issue?
I put valgrind results of ResampleImageFilter2 here:
valgrind --error-limit=no --leak-check=yes -v --show-reachable=yes
