debian woody up to date as of 18.4.02
custom linux kernel 2.4.18 built with gcc 2.95.4
>Description:
This code should be rejected, the bug can be pretty hard to find in complex code:
class Base {
public:
Base(bool) {}
virtual Base* clone() const = 0;
};
class Composition {
Base* basePointer_;
public:
Composition(const Base& basePointer) : basePointer_(basePointer.clone()) {}
};
int main() {
Composition c(false);
}
>How-To-Repeat:
Compile the above code without any compiler options, execute a.out if you care.
>Fix:
Dunno.
