Nope. That kicked it away. Thanks, Bruno! So I guess an object is getting double-destroyed. Probably groff's fault after all. Damn. Still, if I can trigger the crash only with invalid request syntax on a niche platform like Termux, maybe I can justify not hunting this down for groff 1.25.0. I wonder why we'd have an object that gets double-destroyed with Clang 21.1.8 on aarch64, but neither GCC (Debian 10.2.1-6) nor Clang 11.0.1-2 (Debian) on amd64. Regards, Branden
