    Data race detected
The following path leads to a data race:

        VAL             [data={1:0}]

        VAL             [arg={0:0}, arg={0:0}, data={1:0}, data[4]=0, data[4]++=0data[4]++=41]

Now there is a data race, but we were unable to determine exactly which statements and variables are involved. There could be a race between one of the statements
	* C: data[4]++ [686]
	* C: data[4]++ [686]
	* C: data[i]++ [694]
	* C: data[4]++ [686]
	* C: data[4]++ [686]
and
	C: data[4]++ [686]
