Why would a nonlinear programming solver come p with a different solution than a linear programming solver if all the constraints are linear? Isn't a linear programming solver basically a "subset" of a nonlinear programming solver?

    Well, if the function to be optimized is also linear. But, at the end, these are computer programs. Computers hate us. See "I Have No Mouth and I Must Scream" by Harlan Ellison.2012-05-23
