Error: Segmentation fault (core dumped)

[HHendy69]

I'm having some trouble running the path planning code. I tracked the error and the problem is here
fcl::OcTree* tree = new fcl::OcTree(std::shared_ptr<const octomap::OcTree>(tree_oct));
by the way, pkg-config fcl --modversion shows 0.5.0
any Ideas??
