The message "error running gurobi_ampl: termination code 139; core file written" indicates a low-level crash of some kind, such as a segmentation fault. The crash might be in the AMPL-Gurobi interface, or in the Gurobi solver.

Can you provide us with the files that you sent to NEOS, so that we can reproduce the problem and find a fix or workaround? The simplest way is to attach the files to your reply, but if that is not possible or you do not want to make the files public, let me know and I'll set up a private download link.
