            Bug ID: 45085
           Summary: A False Negative case on Array Bound Overflow in Loop
           Product: clang
           Version: 10.0
          Hardware: All
                OS: All
            Status: NEW

Here is a case:

int abv(){
    int a[10];
    int i;
    int max = 10;

    for(i=0; i<=max; i++) {
        a[i]=10; // here i can touch max=10, how to have clang to report it
out.
    }
    return 0;
}

Thanks,
