[C++-sig] exporting a boost::python::dict containing a boost::python::list

[Niall Douglas]

On windows, the only near equivalent to valgrind is Intel's suite of 
very expensive tools. If your company already has a licence, they are 
very good. If not, fire up a copy of Linux on your nearest VM node 
and port a small example of the problem in your BPL app over to GCC.
