@Genoil, if I understand correctly I can not generate DAG file locally (saved on my drive) with 1.1.x version of ethminer? I noticed that if I use latest 1.0.x windows build, I can only generate DAGs up to block 3840000 (-D,--create-dag ) ... if I specify any larger block, ethminer crashes. Is this an issue with Ethereum generally, or an issue with ethminer?
