Seems to do the trick. I can no longer reproduce it after applying that patch. Thanks! Perhaps I should just build Code::Blocks against GTK2. It's unclear to me why it's built against GTK3 in the official package. I don't have anything nice to say about the GTK3 transition, myself, so I'll leave it at that. Cheers
I built the current SVN trunk (11319), and the issue persists. The issue affects a selection of any size, not just the full-page selection.
Version 17.12; Build: Jan 20, 2018, 10:29:55 - wx3.0.3 (Linux, unicode) - 64 bit Installed through Pacman. Backtrace: https://pastebin.com/93J88b1e
Control-A, Control-V crashes Code::Blocks
Awesome. Thanks!
