reflect: method lookup using anonymous field succeeds, but Call crashes #451
Description
by Ostsol:
What steps will reproduce the problem?
package main
import (
"fmt";
"reflect"
)
type A struct {
num int;
str string
}
type B struct {
A
}
func (self *A) Set (num int, str string) {
self.num = num;
self.str = str
}
func CallSet (val interface{}, num int, str string) {
vptr := reflect.NewValue (val).(*reflect.PtrValue);
mthd := vptr.Method (0);
params := []reflect.Value{reflect.NewValue (num), reflect.NewValue
(str)};
mthd.Call (params)
}
func main () {
b := new (B);
CallSet (b, 4, "hi");
fmt.Printf ("%d %s\n", b.num, b.str)
}
What is the expected output? What do you see instead?
This program should output the same as if one called 'b.Set (4, "hi")':
4 "hi"
Instead it produces a runtime panic, declaring:
type mismatch: *main.A != *main.B
What is your $GOOS? $GOARCH?
linux AMD64
