What did you do?
Read the source code at https://github.com/golang/tools/blob/master/go/callgraph/callgraph.go#L92
reflect.Call might be undefined. reflect.Value.Call would be working as expected instead.
What did you expect to see?
// A Edge represents an edge in the call graph.
//
// Site is nil for edges originating in synthetic or intrinsic
// functions, e.g. reflect.Value.Call or the root of the call graph.
