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: *y = 8 [1229]
* C: y = malloc(sizeof(int)) [1236]
* C: *x = 3 [1228]
* C: *x = 3 [1228]
* C: *x = 3 [1228]
* C: x = malloc(sizeof(int)) [1235]
* C: *x = 3 [1228]
and
C: printf("%d\n",*y) [1241]
