Syntax error in my code lets rustc crash

[jeena]

With this example code with a syntax error rustc times out. The g was supposed to be on the next line. This leads to weird behaviour in rls which blocks my whole computer because it consumes a lot of resources.

Code

        let login: gtk::Dialog = gtk::Dialog::new_with_buttons(Some("Login"),
                                                                Some(&widget),
                                                                gtk::DialogFlags::MODAL | g
                                                                tk::DialogFlags::DESTROY_WITH_PARENT |
                                                                gtk::DialogFlags::USE_HEADER_BAR,
                                                                &[cancel_button, login_button]);

I'm attaching a zip with the whole project I had because it's really small so you can reproduce it.
