Data race detected
The following path leads to a data race:
[L1108] 0 char *v;
[L1121] 0 pthread_t t1, t2;
[L1122] FCALL, FORK 0 pthread_create(&t1, 0, thread1, 0)
VAL [pthread_create(&t1, 0, thread1, 0)=-2, t1={5:0}, t2={6:0}, v={0:0}]
[L1123] FCALL, FORK 0 pthread_create(&t2, 0, thread2, 0)
VAL [pthread_create(&t2, 0, thread2, 0)=-1, t1={5:0}, t2={6:0}, v={0:0}]
[L1116] 2 \read(*v)
VAL [arg={0:0}, arg={0:0}, v={0:0}]
[L1111] EXPR, FCALL 1 calloc(8, sizeof(char))
[L1111] 1 v = calloc(8, sizeof(char))
VAL [arg={0:0}, arg={0:0}, calloc(8, sizeof(char))={-3:0}, v={-3:0}, v = calloc(8, sizeof(char))=49]
[L1116] 2 \read(*v)
VAL [arg={0:0}, arg={0:0}, v={-3:0}]
Now there is a data race on ~v~0 between
C: v = calloc(8, sizeof(char)) [1111]
and
C: if (v) strcpy(v, "Bigshot"); [1116]
