Hi, this is a known issue with go 1.17, that was fixed in go 1.17.1. Based on the GOROOT it looks like go 1.17, not 1.17.1, and at 1.17.1 that code does not try to position the ident:
https://cs.opensource.google/go/go/+/refs/tags/go1.17.1:src/go/types/resolver.go;l=279;drc=678b07d5e513a8bbe6780475e88bd92ed1b7b28a

Closing as this looks like a dupe of golang/go#48082. Please reopen if I'm missing something.
