Description (last modified by gkronber)
Similar to #227.
Reproduce in the same way but use RampedTreeCreator.
Effect: The operator can't create a valid tree because the trick of going up in the one tree and going down in the other one won't work with the restricted function library

fixed with r437 by replacing the code to go randomly up in the receiving tree or down in the branch to be inserted with a simple loop that tries random cutting-points until a valid tree is possible.
This has an effect on the bias of the operator, it should be tested if this has a significant effect on the dynamics of GP or not.
