I just encountered a strange thing. I was using a loop that process a buffer.
When the index is outside the buffersize the code should read the next block
from the file and continue. To do this I'm using the modulo operator but there
seems a bug with this.

bl = BufLen % i;

gives following results:
BufLen = 4096
i = 1
bl = 0

i = 2
bl = 0

i = 3
bl = 1 ???????

All variables are unsigned long

I just checked the code and substituted "bl = BufLen % i" with "bl = i / BufLen"
and this works fine.
