Hello,

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
         ls->push_back(av_fetch_point_xy(innerav));
     }
     mls->push_back(*ls);
}
==

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
