[Cbc] [CBC] Access violation solving a small problem with initial solution (CBC release 2.9.5)

[mg]

I can't use valgrind, but Visual Studio indicates that the problem is
located at line 7330 of CbcSolver.cpp :

int n = saveSolver->getNumCols();

and saveSolver is NULL...

Hope this helps...

Marco
