[Cbc] Fwd: Unexpected shut down

[Christos]

Hmm. i am solving the milp problem via initialSolve() and 
branchAndBound()....
So i can not use this command...
I mean that i load problem with solver.loadproblem() and then call 
initialSolve and branchAndBound.

By the way, what is the difference between this operation and
CbcModel model(solver1);
model.initialSolve()
model.branchAndBound()    ?

I am asking because if i choose the 2nd method can not solve the problem 
after B&B is called...
Thank you!
