Data race detected
The following path leads to a data race:
[L1223] 0 int *x;
[L1224] 0 int *y;
[L1225] 0 pthread_mutex_t m = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };
[L1234] 0 pthread_t id;
[L1235] 0 int *z;
[L1236] 0 x = malloc(sizeof(int))
[L1237] 0 y = malloc(sizeof(int))
[L1238] 0 z = y
[L1239] FCALL, FORK 0 pthread_create(&id, ((void *)0), t_fun, ((void *)0))
VAL [#in~arg={0:0}, id={5:0}, m={1:0}, pthread_create(&id, ((void *)0), t_fun, ((void *)0))=-1, x={-3:0}, y={-2:0}, z={-2:0}]
[L1241] EXPR 0 *x
[L1241] EXPR 0 \read(*x)
VAL [#in~arg={0:0}, \read(*x)=26, id={5:0}, m={1:0}, x={-3:0}, y={-2:0}, z={-2:0}]

[L1228] EXPR 1 *x

[L1228] EXPR 1 *x
[L1228] 1 *x = 3
VAL [#in~arg={0:0}, arg={0:0}, m={1:0}, x={-3:0}, y={-2:0}]
[L1229] EXPR 1 *y
[L1229] 1 *y = 8
VAL [#in~arg={0:0}, *y = 8=28, arg={0:0}, m={1:0}, x={-3:0}, y={-2:0}]

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: *x = 3 [1228]
* C: *x = 3 [1228]
* C: *x = 3 [1228]
* C: x = malloc(sizeof(int)) [1236]
* C: y = malloc(sizeof(int)) [1237]
* C: *y = 8 [1229]
* C: *x = 3 [1228]
and
C: printf("%d\n",*z) [1243]
