[Coin-ipopt] Segmentation fault - MA57 interface through Bonmin

[Rodrigo López Negrete de la Fuente]

Hi Andreas,

I'm getting a segmentation fault when using Ipopt with MA57 through Bonmin.
I've pinpointed the problem to the ma57ed_ function call on a second NLP
interation. I'm including the gdb output to see if this helps. Unfortunately
I'm not very experienced in C++ programming so I haven't been able to sole
this. I'm hoping you guys can :).

Thank you very much.

Cheers,
  Rodrigo
