Problem was in the std::vector<text_section> line(std::size_t pos) const method of text_editor.cpp class

 std::cout<<"this->sections_.size = "<<this->sections_.size()<<'\n'; //NEW LINE
if (!(this->sections_.empty())) { //NEW LINE
    sections.emplace_back(this->sections_[pos]);
}

this->sections_.size = 0
this->sections_.size = 0
this->sections_.size = 1
this->sections_.size = 1
