I have a strange error during mining. I'm running solo miner on AMD K10 (Phenom 9650). It is not for profit, more or less, it is for experiments. Anyway, I was able to sync the everything and mining on CPU started successfully. After few hours, (I'm not sure how many exactly) let's say 20h, the daemon stopped with error "Float point exception". I thought it is a random error and started it again. After few hours I got the same error and so on and so on. Monerod (command line tools) is running on linux x86 (Lubuntu) and I'm mining on 1 thread. What exactly this error means and can it be fixed?
