#1600 'Enter' on a specific line crashes desktop environment

[---]

Ubuntu 25.04
Code::Blocks 25.03

I have a cursed .cpp file. If you press enter to make a newline

    void resize((size_t w, size_t h){ <- here
    }

It crashes the desktop environment!

It fails also on Windows with the current trunk, but here it is recoverable just clicking on the editor.

The legacy code completion plugin is the culprit, it works if I remove this code:

                iterator& operator++(){
                    ptr += step;
                    return *this;
                }

                iterator  operator++(int){
                    iterator old = *this;
                    ptr += step;
                    return old;
                }
