As part of resquery_response() refactoring [1], a goto statement was replaced [2] with a call to a new function - originally called rctx_delegation(), now folded into rctx_answer_none() - extracted from existing code. However, one call site of that refactored function does not reset the "result" variable, causing a referral with a non-empty ANSWER section to be inadvertently treated as an error, which prevents resolution of names reliant on servers sending such responses. Fix by resetting the "result" variable to ISC_R_SUCCESS when a response containing a non-empty ANSWER section can be treated as a delegation. [1] see RT #45362 [2] see commit e1380a16741a3b4a57e54d7a9ce09dd12691522f
