When starting a closure that needs a dictionary, copy the closure variable to a local variable. This lets child closures capture that dictionary variable correctly. This is a better fix for #47684, which does not cause problems like #47723. Fixes #47723 Update #47684 Change-Id: Ib5d9ffc68a5142e28daa7d0d75683e7a35508540 Reviewed-on: https://go-review.googlesource.com/c/go/+/343871 Trust: Keith Randall <khr@golang.org> Trust: Dan Scales <danscales@google.com> Run-TryBot: Keith Randall <khr@golang.org> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Dan Scales <danscales@google.com>
