[BUG] Ethash-Lowmemory mining on Prohashing fails

[RainbowMiner]

TBMiner.exe --algo ethash --hostname eu.prohashing.com --port 3358 --wallet xyz --worker-name abc --server-passwd a=ethash-lowmemory,n=abc --cuda-devices [0]

.. leads to a pool error message:

Running any other Ethash miner (Trex, Ethminer, Gminer, ...) with the above configuration works. Mining Etchash with TBminer on Prohashing works

I have also reported this issue with ProHashing support. It seems to be a general problem with EthashLowMem algo. Other miners (PhoenixMiner, TTMiner & NanoMiner also fail) Edit: However GMiner 3.05 works.

fixed in v1.69
