Thanks for the comment. Do you mean the test cases (generic/628 and generic/629) need fix to call _require_scratch*() before _require_dm_target()? I think that fix approach will leave the possibility that the newly added test cases in the future may have the same failure. IMO, the patch posted will be more effective to prevent the failures. -- Best Regards, Shin'ichiro Kawasaki
