boost::shared_ptr<VanillaOption> makeOption(....)
{
  switch (engineType) {
  case CRR:
    engine = boost::shared_ptr<PricingEngine>(
      new BinomialVanillaEngine<ExtendedCoxRossRubinstein>(..));
  case EQP:
    engine = boost::shared_ptr<PricingEngine>(
      new BinomialVanillaEngine<
        ExtendedAdditiveEQPBinomialTree>(..));
    break;
  ....
}

The break operator is missing.
