I see this as well. It triggers a lot when using boost::graph which
uses empty classes as tags all over the place. A simple case with
boost::graph would be this:
--------------------------
#include <boost/graph/adjacency_list.hpp>
using namespace boost;
adjacency_list<vecS, vecS, undirectedS,
property<vertex_color_t, default_color_type,
property<vertex_degree_t,int> > > g;
void create_graph () { add_edge(1,2, g); }
--------------------------
boost/graph/detail/adjacency_list.hpp: In function 'void create_graph()':
boost/graph/detail/adjacency_list.hpp:819: warning: 'p' may be used
uninitialized in this function
boost/graph/detail/adjacency_list.hpp:2210: note: 'p' was declared here
This problem makes -Wuninitialize pretty much useless for anyone who uses
boost::graph. I think it would be a shame if we shipped a compiler that
has a problem with this.
