c++ - Segmentation fault when trying to remove element from a list -

in order solve this problem have, wrote little piece of code:

for (std::list<std::vector<int>>::iterator = l.begin(); != l.end(); ++i) {   (std::list<std::vector<int>>::iterator j = next(i, 1); j != l.end(); ++j) {     if (includes((*j).begin(), (*j).end(), (*i).begin(), (*i).end())) {       l.erase(j++);     }   } } 

the basic idea is, given element of list, remove elements rest of list matches criteria (in case, containment relation).

executing triggers segmentation fault, can't understand. can give me clue this?

the comment right, thanks. corrected code is:

for (std::list<colset>::iterator = l.begin(); != l.end(); ++i) {   std::list<colset>::iterator j = next(i, 1);   while (j != l.end()) {     if (includes((*j).begin(), (*j).end(), (*i).begin(), (*i).end())) {       j = l.erase(j);     }     else {       ++j;     }   } }
