Data race detected
The following path leads to a data race:
[L917] 0 int myglobal1;
VAL [myglobal1={1:0}]
[L918] 0 int myglobal2;
VAL [myglobal1={1:0}, myglobal2=0]
[L919] 0 pthread_mutex_t mutex1 = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };
VAL [mutex1={2:0}, myglobal1={1:0}, myglobal2=0]
[L920] 0 pthread_mutex_t mutex2 = { { 0, 0, 0, 0, 0, { { 0, 0 } } } };

[L931] 0 pthread_t id;
VAL [mutex1={2:0}, mutex2={3:0}, myglobal1={1:0}, myglobal2=0]
[L932] FCALL, FORK 0 pthread_create(&id, ((void *)0), t_fun, ((void *)0))
VAL [id=-1, mutex1={2:0}, mutex2={3:0}, myglobal1={1:0}, myglobal2=0]
[L927] CALL 1 munge(&mutex1, &myglobal1)
[L923] EXPR 1 \read(*v)
VAL [\old(m)={2:0}, \old(v)={1:0}, m={2:0}, mutex1={2:0}, mutex2={3:0}, myglobal1={1:0}, myglobal2=0, v={1:0}]
[L923] EXPR 1 *v+1
VAL [\old(m)={2:0}, \old(v)={1:0}, m={2:0}, mutex1={2:0}, mutex2={3:0}, myglobal1={1:0}, myglobal2=0, v={1:0}]
[L923] 1 *v=*v+1

[L933] CALL 0 munge(&mutex2,&myglobal1)
[L923] EXPR 0 \read(*v)

[L923] 1 *v=*v+1

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: *v+1 [923]
* C: *v+1 [923]
* C: *v+1 [923]
* C: *v+1 [923]
and
C: *v=*v+1 [923]
