Comment (by stefan):

 I also get the correct optimal value, but the returned solution does not
 correspond to it.

 In my original interface, I also use this !CouenneRecordBestSol
 workaround, but it still gives an incorrect solution point.

 Do you get a correct solution when using Couenne with CPLEX?
