[Ipopt] Restoration Failed

Hi Ali,

I have both 3.6.1 and 3.7.0 installed.
However, I get exactly the same behavior with either one.

My greatest problem with this bug, is that it seams to be non 
deterministic, in the sense that, when I get a "Restoration failed" on 
one run, if I run the solver again with exactly the same conditions, it 
is very probable that I'll get an "Optimal solution found".
