Subject: [geometry] Populating and destructing multi geometries
From: Alessandro Ranellucci (alex_at_[hidden])

I'm the maintainer of the Perl bindings (Boost::Geometry::Utils)
and I'm tracking down a memory leak that I introduced in the
code that transforms Perl data structures to multi_linestring geometries.

First off, I couldn't find any examples about how to populate
multi geometries. This is what I'm doing now:

multi_linestring* mls = new multi_linestring();
for (...) { // loop through lines in Perl data structure
     linestring* ls = new linestring();
     for (...) { // loop through points in Perl data structure

Does this look correct?

Now, how am I supposed to delete the multi_linestring object
with all of its linestrings? 'delete mls' doesn't seem to free everything.
Am I supposed to walk it myself and delete the individual linestrings?

Thank you very much in advance,

- Alessandro
