- DataRaceFoundResult [Line: 931]: Data race detected
Data race detected
The following path leads to a data race:
[L917] 0 int myglobal;
VAL [myglobal={1:0}]
[L918] 0 pthread_mutex_t mutex1 = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };
VAL [mutex1={2:0}, myglobal={1:0}]
[L919] 0 pthread_mutex_t mutex2 = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };
VAL [mutex1={2:0}, mutex2={3:0}, myglobal={1:0}]
[L928] 0 pthread_t id;
VAL [id={5:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}]
[L929] FCALL, FORK 0 pthread_create(&id, ((void *)0), t_fun, ((void *)0))
VAL [arg={0:0}, id={5:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}, pthread_create(&id, ((void *)0), t_fun, ((void *)0))=-1]
[L931] EXPR 0 \read(myglobal)
VAL [\read(myglobal)=0, arg={0:0}, id={5:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}]
[L931] EXPR 0 myglobal+1
VAL [\read(myglobal)=0, arg={0:0}, id={5:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}]
[L931] 0 myglobal=myglobal+1
VAL [\read(myglobal)=0, arg={0:0}, id={5:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}, myglobal=myglobal+1=25]
[L921] 1 int *p = &myglobal;
VAL [arg={0:0}, arg={0:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}, p={1:0}]
[L923] EXPR 1 \read(*p)
VAL [\read(*p)=1, arg={0:0}, arg={0:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}, p={1:0}]
[L923] 1 *p + 1
VAL [\read(*p)=1, arg={0:0}, arg={0:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}, p={1:0}]
[L931] 0 myglobal=myglobal+1
VAL [\read(*p)=1, \read(myglobal)=0, arg={0:0}, arg={0:0}, id={5:0}, mutex1={2:0}, mutex2={3:0}, myglobal={1:0}, myglobal=myglobal+1=25, p={1:0}]
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: *p + 1 [923]
* C: myglobal+1 [931]
* C: myglobal+1 [931]
* C: myglobal+1 [931]
* C: myglobal+1 [931]
and
C: myglobal=myglobal+1 [931]
