Subject: [Boost-users] [bind] an easy way to break ORD ? (where am i wrong?)

>From http://www.boost.org/doc/libs/1_37_0/libs/bind/bind.html#Synopsis :
namespace
{
unspecified-placeholder-type-1 _1;
unspecified-placeholder-type-2 _2;
unspecified-placeholder-type-3 _3;
// implementation defined number of additional placeholder definitions
}
Then I use placeholders like this:
class X {
void h(int);
void f1() {
return boost::bind(&X::h, this, _1)(3);
}
}
As f1 is inline, it should be the same in all the translation units, to obey
ODR.
However, anonyomous namespace is different in a different translation unit,
so _1 is different variable.
Is One Definition Rule broken ?
