[geos-devel] Was it a big memory leak ?

[Yury A. Bychkov]

Good news. I was wondering why my memory leak detector didn't complain about
that. Since that FAQ says that disabling the caching will slow down things
considerably, we should probably leave it as it is.

BTW, can you send a message to the list once you finish cascade-patching for
getCoordinates(), so that I can start on fixing the leaks it caused (when I ran
the current code on my big test file (1673 tests) I've got 55162 leaks) ?
