The same suggestion applies to the cases where a non-const method is called
from a const method, such as in the example below:

<code>
class Foo {
        void bar1() {}
        void bar2() const {
                bar1();
        }
};

int main()
{
        return 0;
}
</code>

The same error message is returned:
<message>
main.c++: In member function âvoid Foo::bar2() constâ:
main.c++:4:22: error: passing âconst Fooâ as âthisâ argument of âvoid
Foo::bar1()â discards qualifiers [-fpermissive]
</message>
