iOS objc_msgSend crash, with no report or warning given -


i testing app out, pushing pretty hard, , i'm getting crash (black screen, image doesn't save, drops springboard). however, no crash reports logged in console. when test using profiler message saying target died, gives no clues.

in organiser got device crash logs gives me believe telling me i'm sending message i've released (objc-msgsend + 22)? on right track here?
