I could see two kinds of false positives with this checker when running this on
the LLVM codebase.
When objects are allocated in a way that one object is allocated together with
an array (the array is after the original object in), and the object contains
getter code like:
reinterpret_cast<Elements*>(this + 1);
When a function is written like this:
Obj* f() {
if (opaqueCond)
return singleObject;
return array;
}
And used like this:
f()[5];
Other then these two cases I think the results are good.
