I think this is as simple as possible:
sort(keys.begin(), keys.end(), greater<int>());
  // maybe use std::unique to remove duplicates
  BOOST_FOREACH(int key, keys)

      assert(key >= 0);
      assert(key < data.size());
      data.erase(boost::next(data.begin(), key));

I think it's also wrong. You need to walk the index list backwards 
because otherwise you change the indices of the data vector and remove 
the wrong elements.

Hmm... I think you missed the sort call, just before FOREACH.
