Description
If found this while manipulating goblint.
When running goblint with ana.arrayoob set to true I found out that this code:
#include <stdio.h>
int table[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
int main() {
for (int i = 0; i < sizeof(table); i++) {
table[i] = 0;
}
printf("\n");
return 0;
}Causes a warning to appear which is normal. But this code:
#include <stdio.h>
int table[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
int main() {
for (int i = 0; i < sizeof(table); i++) {
printf("%d ", table[i]);
}
printf("\n");
return 0;
}Doesn't trigger any warning. Turns out that it does the same with other types of warning. For instance, with ana.int.interval:
#include <stdio.h>
#include <limits.h>
int main() {
int a = INT_MAX + 1;
return 0;
}Causes a warning, while
#include <stdio.h>
#include <limits.h>
int main() {
printf("%d\n", INT_MAX + 1);
return 0;
}don't
