This test runs independent goroutines modifying a comprehensive variety of local vars to look for garbage collector regressions. This test has been verified to trigger issue 22781 on the go1.9.2 tag. This test expands on test/fixedbugs/issue22781.go. Tests #22781 Change-Id: Id32f8dde7ef650aea1b1b4cf518e6d045537bfdc Reviewed-on: https://go-review.googlesource.com/93715 Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
