Same here. Even with the -wd flag set it doesn't shut shut down the miner - it just hangs in mid-work. Seemed to happen randomly for me. Once after about a 15 minutes. Another time after about 2 hours. Switched back to 1.2.

Incidently, anay's suggestion about lowering the GPU_MAX_ALLOC_PERCENT to 80 worked magic for me. My 3x7950's went from 730 h/s to 890 h/s on that change alone.
