The following path leads to a data race:
[L917] 0 int myglobal;
[L918] 0 pthread_mutex_t mutex1 = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };
[L919] 0 pthread_mutex_t mutex2 = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };
[L928] 0 pthread_t id;
[L929] FCALL, FORK 0 pthread_create(&id, ((void *)0), t_fun, ((void *)0))
VAL [arg={0:0}, id={3:0}, mutex1={1:0}, mutex2={2:0}, myglobal=0]
[L922] EXPR 1 myglobal+1
VAL [arg={0:0}, arg={0:0}, mutex1={1:0}, mutex2={2:0}, myglobal=0]
[L931] 0 myglobal+1
