>Description:
The following code compiles:

struct foo
{
    void bar() {}
    int bar() {return 0;}
};

int main() {}

It should generate an error as two functions differing only in their return value are not permitted.

If the functions are not declared inline (i.e. outside the class) the assembler complains because the two functions have the same name; if the functions are used, a proper error message is emitted.

The same happens with g++ 3.0; g++ 2.95 recognizes the problem and emits an error message.
>How-To-Repeat:
Compile this snippet with no compiler flags:


struct foo
{
    void bar() {
    }

    int bar() {
        return 0;
    }
};

int main() {}
