Not sure why this isn't happening on TryBots, but this is what I'm seeing when I run locally on macOS or Linux:

I could reproduce the bug using Git only:

#!/usr/bin/env bash

set -euo pipefail

rm -rf repo
mkdir repo
cd repo
git init --bare
git remote add origin -- https://go.googlesource.com/text
git fetch -f --depth=1 origin refs/tags/v0.2.0:refs/tags/v0.2.0
got=$(git -c log.showsignature=false log -n1 '--format=format:%H %ct %D' c4d099d611ac --)
want='c4d099d611ac3ded35360abf03581e13d91c828f 1513160748 grafted, tag: v0.2.0'
if [ "$got" != "$want" ]; then
  echo "got:  $got" >&2
  echo "want: $want" >&2
  exit 1
else
  echo ok >&2
fi

This may be a bug with the version of Git installed on my machine. I couldn't reproduce this with Git 2.32.0.

Is this marked as a 1.18 release blocker because it's okay to fix this after 1.17 is released?

I can't reproduce with git version 2.30.1 (Apple Git-130) either.

Ah, meant to mark this for 1.17.

I'm removing the release-blocker label, since this seems to be a bug in Google's Git, not in Go, and I don't expect we'll need to change anything.

Reported internally as b/193836680.

Thanks for reporting. https://lore.kernel.org/git/YO8RaMj7sN4ABe5d@coredump.intra.peff.net/ should fix this.

The buggy commit was not part of any Git release, so cmd/go shouldn't need to work around it.

Thanks @jrn! I'll close this issue then.
