Re: [Boost-users] [multi-index][foreach] Iterating over a sequence index (worked in 1.46, broke in 1.47)

typedef multi_index_container< int, indexed_by< sequenced<> > > bmi_t; typedef bmi_t::nth_index<0>::type seq_idx;

const seq_idx& ret(const seq_idx& idx) { return idx; }

int main() {

 bmi_t b;

 seq_idx& seq = b.get<0>();

 // Works  BOOST_FOREACH (int i, seq)    std::cout << i << std::endl;

 // Doesn't compile  BOOST_FOREACH (int i, ret(seq))    std::cout << i << std::endl; }

It seems that gcc attempts to copy the index, for some reason. BTW, your code compiles well with VC10.
