Hi Martin,

Are you sure, that there already exists a primal solution at this point?
Otherwise, sol would be set to NULL and you would get the solution
values of the current LP solution.
If sol is set to NULL, please print the value of SCIPgetLPSolstat(), if
the LP is not solved to optimality (value 1), there might be saved an
infeasible primal solution.
If sol is not NULL, please check which heuristic found the solution, by
printing SCIPheurGetName( SCIPsolGetHeur(sol) ).
Do you use lazy bounds?
Best, Gerald
