New issue 419 by piiguu: Two handles are equal even when they refer to
different objects
http://code.google.com/p/v8/issues/detail?id=419
The function below in Handle<T> class always returns true even two handles
refer to different objects
/**
* Checks whether two handles are the same.
* Returns true if both are empty, or if the objects
* to which they refer are identical.
* The handles' references are not checked.
*/
template <class S> bool operator==(Handle<S> that) const {
void** a = reinterpret_cast<void**>(**this);
void** b = reinterpret_cast<void**>(*that);
if (a == 0) return b == 0;
if (b == 0) return false;
return *a == *b;
}
Repro:
#include <v8.h>
#include <stdio.h>
class A
{
};
class B
{
};
int main()
{
A a;
B b;
Handle<A> ha(&a);
Handle<B> hb(&b);
if (ha == hb)
printf("equal!");
return 0;
}
