What did you do?

package main

import "fmt"

var v int

func main() {
	v = 5
	fmt.Println("hello world!", v)
}

Then find references for v.

What did you expect to see?

Three results:

{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:4, Character:4},
        End:   protocol.Position{Line:4, Character:5},
    },
},
{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:8, Character:29},
        End:   protocol.Position{Line:8, Character:30},
    },
},
{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:7, Character:1},
        End:   protocol.Position{Line:7, Character:2},
    },
},

What did you see instead?

Four results: the declaration is returned twice:

{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:4, Character:4},
        End:   protocol.Position{Line:4, Character:5},
    },
},
{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:4, Character:4},
        End:   protocol.Position{Line:4, Character:5},
    },
},
{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:8, Character:29},
        End:   protocol.Position{Line:8, Character:30},
    },
},
{
    URI:   "file:///home/myitcv/gostuff/src/github.com/myitcv/playground/main.go",
    Range: protocol.Range{
        Start: protocol.Position{Line:7, Character:1},
        End:   protocol.Position{Line:7, Character:2},
    },
},
