Previously, an inlined call to wg.Done() in package main would have the following incorrect symbol name: main.(*sync.WaitGroup).Done This change modifies methodname to return the correct symbol name: sync.(*WaitGroup).Done This fix was suggested by @mdempsky. Fixes #19467. Change-Id: I0117838679ac5353789299c618ff8c326712d94d Reviewed-on: https://go-review.googlesource.com/37866 Reviewed-by: Austin Clements <austin@google.com>
