hello, i suspect there is something wrong with assign routine in compressed_sparse_row_graph.hpp. when i am constructing directed csr from undirected one via // From any graph (slow and uses a lot of memory) // Requires IncidenceGraph, a vertex index map, and a vertex(n, g) function // Internal helper function template<typename Graph, typename VertexIndexMap> void assign(const Graph& g, const VertexIndexMap& vi, vertices_size_type numverts, edges_size_type numedges) { inherited_vertex_properties::resize(numverts); m_rowstart.resize(numverts + 1); m_column.resize(numedges); it overwrites non-allocated memory, because the number of edges is in fact doubled.. is it an imperfection or am i doing something stupid? have a nice day, mojmir
