[Boost.Graph] Custom vertex properties with std::shared_ptr member ?

Hi,

struct CustomVertex {
std::string name;
std::shared_ptr<AbstractNodeClass> _node;
};
typedef boost::adjacency_list < boost::vecS,
boost::vecS,
boost::bidirectionalS,
CustomVertex> Graph;

Vertex DGManager::createVertex(const std::string &name,
std::shared_ptr<AbstractNodeClass>
Ptr)
{
_activeVertex = boost::add_vertex(CustomVertex{name, nodePtr}, _g);
return _activeVertex;
}

  With Visual Studio 2017, the above is fine but with GCC 7.5.0, I get a
seg-fault on application exit. Looking at the stack trace, it looks like a
problem in the CustomVertex destructor.

  Is there some restriction as to what types we can use as member variable
of Custom Vertex Properties ?

Kind regards
