Re: [Boost-users] Modifying all matching elements in a Boost.MultiIndex Container

std::pair<index::iterator, index::iterator> iter = index.equal_range(value);

while(iter.first != iter.second) {

  index.modify(     iter.first,     [](T& element) { ... }   );

  iter.first++; }

leads to segfaults and unexpected behavior.

What would be right way to approach this?
