Constant definition loop with grpc package

[alexeyvale]

The following program triggers an unexpected result

package main

// yaegi:tags purego appengine

import "google.golang.org/grpc"

func main() {
}

Expected result

Nothing happens with no errors.

Got

Additional Notes

I saw similar issue, but it is closed, and the problem still persists. The program was run with Eval method of interp.Interpreter.
