It would only be useful if that bug report included a way to reproduce
the problem. And it would probably be helpful to discuss that code
example beforehand.

I am not saying that there are no memory leaks in GIMP. But we are
frequently testing the software for this and I am not aware of any major
memory leaks such as the one that Bill describes here.

Actually, it doesn't do that when space is needed, but when the memory
allocated for tiles exceeds the limit configured as 'tile-cache-size'.
