Data race detected
The following path leads to a data race:
[L918-L921] 0 struct {
int x;
int y;
} data;
VAL [data={1:0}]
[L927] 0 int *i,j = __VERIFIER_nondet_int();
VAL [data={1:0}]
[L927] 0 int *i,j = __VERIFIER_nondet_int();
VAL [__VERIFIER_nondet_int()=1, data={1:0}, j=1]
[L928] 0 pthread_t id;
VAL [data={1:0}, id={5:0}, j=1]
[L929] COND TRUE 0 \read(j)
VAL [data={1:0}, id={5:0}, j=1]
[L929] 0 i = &data.x
VAL [data={1:0}, i={1:0}, id={5:0}, j=1]
[L931] FCALL, FORK 0 pthread_create(&id, ((void *)0), t_fun, ((void *)0))
VAL [arg={0:0}, data={1:0}, i={1:0}, id={5:0}, j=1, pthread_create(&id, ((void *)0), t_fun, ((void *)0))=-1]
[L923] EXPR 1 data.x

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.x++ [923]
* C: (*i)++ [932]
* C: data.x++ [923]
* C: data.x++ [923]
* C: data.x++ [923]
and
C: data.x++ [923]
