Data race detected
The following path leads to a data race:
[L689] 0 int mutex;
VAL [mutex=0]
[L690] 0 int res;
VAL [mutex=0, res=0]

[L726] EXPR 1 res < 10
VAL [\old(arg)={0:0}, arg={0:0}, mutex=0, res=0]
[L736] FCALL, FORK 0 pthread_create(&t, 0, thr2, 0)
VAL [mutex=0, res=0, t=-1]
[L736] FCALL, FORK 0 pthread_create(&t, 0, thr2, 0)
VAL [mutex=0, res=0, t=0]

[L694] 2 mutex = 1
[L717] RET 2 __VERIFIER_atomic_acquire()
[L718] CALL, EXPR 2 pf(4,3)
[L704] 2 return a+b+1;
VAL [\old(a)=4, \old(b)=3, \result=8, a=4, b=3, mutex=1, res=0]
[L718] RET, EXPR 2 pf(4,3)
[L718] 2 res = pf(4,3)

[L726] COND FALSE 1 !(!(res < 10))

[L726] 1 res < 10

[L726] 1 res < 10
VAL [\old(arg)={0:0}, arg={0:0}, mutex=1, res=8]
Now there is a data race on ~res~0 between
C: res = pf(4,3) [718]
and
C: res < 10 [726]
