Mateusz,
IMO you're on the right track with the idea that
MCIndexSegmentSetMutualIntersector owns the segChains that it
allocates. They can be deleted in it's destructor.
I don't see the design problem. What's wrong with having complex
long-lived structures which allocate internal objects, and then free
them when the structure is itself destroyed?

Folks,
I've started memory leaks cleanup [1] in GEOS and found quite serious
design issue around MonotoneChain components.
Here is longer story [2] with suggested solution, however I'm not enough
knowledgeable about all internals especially about possible relations
between various collections allocated internally as well as flows and
ownership transfers.
I'd be thankful if original authors of these components (Ben?, Sandro?)
could share their minds.
