When I solve my model, I get a stack overflow error/core dump/protection error. What is wrong?

If your model has integer/binary/semi-cont/SOS variables then version 5 can solve your problem. In version 4, the implemented branch-and-bound algorithm puts its branches on the stack and that can result in a stack overflow when it is a tough model. Version 5 doesn’t put the branches on the stack anymore and because of that, this error is solved.
