If the LP-relaxation of the given MIP is infeasible, SYMPHONY thinks its
an computational instability (lp_genfunc.c). It dumps MPS file and says:
****************************************************
* Terminated abnormally with error message -252 *
* Now displaying stats and best solution found... *
****************************************************
It should say problem is infeasible.
Its a blocker for me since i need to check a lot of infeasible problems.
