Hi, I was wondering what the common causes were of the above error?
Im running a DFS search on an unsolvable problem, and have a global constraint of my own design, along with some distinct constraints. Some time into the search, i return ES_FAILED from my propagate function(not for the first time), which is usually followed by a my propagators copy constructor being called, followed by my Space's copy method. However, in this case i get: "Exception: Space::clone: Attempt to invoke operation on failed space." just after my propagate method returns ES_FAILED. I realize that im not providing adequate information to debug this problem, but perhaps you could give me a hint on what could cause this?
