What did you do?
I use a closure to handle an interface, which writes a map.
The minimum reproduce code like:
package main
type Header interface {
Set(key, value string)
}
type MockHeader struct {
info map[string]string
}
func New() Header {
return &MockHeader{
info: map[string]string{},
}
}
func (h *MockHeader) Set(key, value string) {
h.info[key] = value
}
func main() {
foo := func() Header {
m := New()
m.Set("test", "12345")
return m
}()
_ = foo
}
According to my test, three conditions need to be met will trigger this error:
- use closure
- use an interface , like the
type Header interface in my code
- write the map
If the New return a struct pointer directly, it will be ok.
If the write maps like Set is out of closure, it will be ok.
If the function is not a closure but a normal function, it will be ok
What did you expect to see?
build success.
What did you see instead?
go build bug.go
# command-line-arguments
./bug.go:25:22: internal compiler error: order.stmt CALLMETH
Please file a bug report including a short program that triggers the error.
