What did you do?
I was getting file and line of struct method.
https://go.dev/play/p/VFs8FKAkTLf
package main
import (
"reflect"
"runtime"
)
type s struct{}
func (tc *s) f() {}
func main() {
tc := &s{}
v := reflect.ValueOf(tc.f)
ptr := v.Pointer()
f := runtime.FuncForPC(ptr)
file, line := f.FileLine(f.Entry())
name := f.Name()
println(file, line, name)
}What did you expect to see?
.../main.go 10 main.(*s).f-fm
What did you see instead?
<autogenerated> 1 main.(*s).f-fm
The issue is reproducible with go1.18 and gotip, however go1.18rc1 and below (go1.17) works as expected.
