Data race detected
The following path leads to a data race:
[L917] 0 int global;
VAL [global=0]
[L920] 0 void (*f)() = good;
VAL [f={-1:0}, global=0]
[L926] 0 pthread_t id;
VAL [f={-1:0}, global=0]
[L927] FCALL, FORK 0 pthread_create(&id, ((void *)0), t_fun, ((void *)0))
VAL [f={-1:0}, global=0, id=-1]
[L928] 0 f = bad
VAL [f={-1:2}, global=0, id=-1]
[L928] 0 f = bad
VAL [f={-1:2}, global=0, id=-1]
[L922] 1 f()
VAL [\old(arg)={0:0}, arg={0:0}, f={-1:2}, global=0]
Now there is a data race on ~f~0 between
C: f = bad [928]
and
C: f() [922]
