That is most likely because your copy of gimp-2.3 has debugging symbols
while your copy of gimp-2.2 doesn't. I wouldn't be surprised if gimp-2.3
uses a little more memory than gimp-2.2 but the difference should be
marginal.

I have tested this in valgrind and it doesn't show me any memory leaks.
Can you reproduce this with G_SLICE=always-malloc ?
