@erichkeane Correct me if I am wrong.
In here, this is the current scenario
```
if (int *ptr = get_something()) {
return ptr[0];
}
else if (int *ptr2 = get_something_else()) {
return ptr[0] * ptr2[0]; //warns for ptr
}
else if (int *ptr3 = get_something_else_again()) {
return ptr[0] * ptr2[0] * ptr3[0]; // warns for ptr and ptr2
}
else if (int *ptr4 = get_something_else_again_now()) {
return ptr[0] * ptr2[0] * ptr3[0] * ptr4[0]; // warns for ptr, ptr2
and ptr3
}
```
It should warn for something else too?
