Never mind. As usual, had nothing to do with optimization... The issue with bundled properties does seem real however. THK On Fri, Sep 6, 2013 at 3:15 PM, Tim Keitt <tkeitt@gmail.com> wrote:
I'm getting seg faults when I use optimization with floyd_warshall_shortest_paths. Without optimization it works fine.
d here is defined as
struct dmat_t { typedef std::vector<edge_weight_t> storage_t; dmat_t(vertex_t n) : ncol(n), storage(n * n) {} storage_t::iterator operator[](vertex_t row) { assert(row < ncol); storage.begin() + row * ncol; } vertex_t ncol; storage_t storage; };
Is this from 'inf' getting optimized out or how I defined dmat_t?

Also, it does not seem that floyd_warshall_shortest_paths is compatible with bundled properties.
