Looks like the error happens on generating the model. Try to run
glpsol with the option '--check', and if there will be the same
picture, check constraints 'constx' and 'consty' as well as sets,
parameters, and/or variables they refer to more carefully.

If you wish, you can post your model to me. Then I could say
something more definite.
