This FTBFS is not a bug in honnef. The Go compiler stores type information in what it calls export data, and that format is versioned. golang-1.27 2:1.27.2-1 started writing version 5. honnef's tests read that data through golang-golang-x-tools, and 0.49.0 only understands version 4, so they fail.
golang-golang-x-tools 1:0.52.0+ds-1 understands version 5 and is now in unstable. With it, golang-honnef-go-tools 2026.2.1-2 builds unchanged in a clean chroot: Status successful. Juan
