I am solving lp and mip problems interchangeably. I found a strange bug for problems with redundant row. After solving lp, if I change problem to mip and solve it, I get a suboptimal solution.

Please see attachments to reproduce result. 

What version of CPLEX do you use? What is the suboptimal solution you get? Do you get solution status 101 or something else when you observe the suboptimal solution?

I tried with CPLEX 12.4, 12.5, 12.6 and I always get solution status 101 and objective 3089 as optimal solution, which I think is the correct one.
