[geos-devel] Unclear objects lifetime and ownership issues in Monotone Chain components

[Mateusz Loskot]

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.
