I suspect it is not a simple case, since this compiles fine:
typedef std::map<std::wstring, std::wstring> wsm;
wsm sm_;
BOOST_FOREACH(const wsm::value_type &sv, sm_) {
        wcslen(sv.first.c_str());
}

The problem occurs where I have used Multindex to define maps (the value type
is a pair-like class that has the 'second' member is marked mutable, because
Multindex containers only expose the contained data as const).

Oh, and it compiles with BOOST_FOREACH_NO_RVALUE_DETECTION defined.

Thanks
