For COM API users, ISymbolLookupExpressionBuilder appears to be broken. For example,

GF_Api_COM::ISymbolLookupExpressionBuilderPtr expressionBuilder;
expressionBuilder.CreateInstance(__uuidof(GF_Api_COM::SymbolLookupExpressionBuilder));
CComSafeArray kinds(10);
kinds.Add(GF_Api_COM::ContractKind_Future);
expressionBuilder = expressionBuilder->WithContractKinds(kinds);

...will cause an exception to be thrown. This appears to be a known bug since this sort of operation has been commented out in the CppCOMSample project in the file CppCOMSampleDlg.cpp around line 671.

Is there a fix coming from this soon or is there an alternate method to limit the kinds of contracts returned by GFAPI()->Contracts->Lookup->ByCriteria?

To be clear - it appears that it's only the WithContractKinds method that's broken.

We now see that this is a problem, and are working on it.
