yes

if you declare both vars and cuts in the core, i am pretty sure you also 
have to declare the matrix (i.e., describe the rows as well) to 
BCP_lp_relax*& matrix... check out the construction in Examples/BranchAndCut

i should also be posting an update to the Lehigh tutorial in the next 
week (or two) which will have some very simple BCP examples
