[SCIP] lp error when adding locally constraint

Hi there,

I am using scip-6.0.1 for my research work. After creating local constraints by setting paramter <local> to true and adding them to nodes, the SCIP terminates after processing a number of nodes. The error is "corrupted size vs. prev_size" and is in inside the soplex solver. My workaround is setting the parameter initial to false so that the constraint is not added to lp. It works but I don't know whether that local constraint is still effective (prune all nodes that is invalid under this local constraint by propagation or other checks). I need to make sure the local contraint is fully effective over the tree whose root is added that local constraint.

Thanks,
yunzhuang
