Dear OpenMesh maintainers, When assigning a mesh as follows meshB.assign_connectivity(meshA); with meshA comprising a vertex status property, meshB.release_vertex_status(); makes OpenMesh crash. The reason seems to be that meshB has a "valid" vertex status property handle, but not a vertex status property. I attached a minimal example to reproduce. I suspect this bug to have been introduced by this commit https://graphics.rwth-aachen.de:9000/OpenMesh/OpenMesh/commit/29cbe820484... best regards, Simon
