  - DataRaceFoundResult [Line: 931]: Data race detected
    Data race detected
The following path leads to a data race: 
[L917]               0  static int data1;
        VAL             [data1=0]
[L918]               0  static int data2;
        VAL             [data1=0, data2=0]
[L919]               0  static pthread_rwlock_t rwlock = { { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 } };
        VAL             [data1=0, data2=0, rwlock={1:0}]
[L928]               0  pthread_t id;
        VAL             [data1=0, data2=0, rwlock={1:0}]
[L929]  FCALL, FORK  0  pthread_create(&id, ((void *)0), t_fun, ((void *)0))
        VAL             [\old(arg)={0:0}, data1=0, data2=0, id=-1, rwlock={1:0}]
[L922]               1  data1++
        VAL             [\old(arg)={0:0}, arg={0:0}, data1=0, data2=0, rwlock={1:0}]
[L922]               1  data1++
        VAL             [\old(arg)={0:0}, arg={0:0}, data1=1, data2=0, rwlock={1:0}]
[L931]               0  printf("%d",data1)
        VAL             [\old(arg)={0:0}, arg={0:0}, data1=1, data2=0, id=-1, rwlock={1:0}]

Now there is a data race on ~data1~0 between 
	C: data1++ [922]
and
	C: printf("%d",data1) [931]
