The code there is weird but my C++ is rusty so I don't know if it's permissible to do (but Google says it's UB so maybe it was a coincidence that it worked before): Proto::Proto() calls SFNode::SFNode(NULL) which calls ->ref0() on this NULL, the said method specifically checking for "this != NULL". whitedune 0.30.10 was uploaded to Debian in 2011, the current version (the new homepage is https://wdune.ourproject.org/) is 1.956, released, I assume, in 2020, and its SFNode::SFNode() doesn't do this anymore. I don't see a VCS so I can't find a change that did this.
