This is standard behaviour of std::map. The non-const operator[] inserts the
element if it is not there. If you have been bitten by it once you won't
forget...

Example:
class Foo {
void Fun(Foo const &);
};
class Bar {
void DoSomething();
void Fun(Foo const &);
};
Bar::DoSomething()
{
std::vector<Foo> x;
for_each(x.begin(), x.end(), std::mem_fun_ref(&Foo::Fun));
for_each(x.begin(), x.end(), boost::bind(&Bar::Fun, this, _1));
}
The case we have here is the second. Clear now?
