#### D.4.3 `glpk` errors

Possible error messages are

         <'bad glpk specification'>

which means that the input did not conform to the description given above, and

         <'memory overflow'>

It is not considered an exceptional condition for no feasible solution to exist, and in that case an empty list is returned.

The `glpk` documentation gives no assurance as to the correctness of reported solutions, so the user should also take the possibility of incorrect results into account.
