/cc @michaelmatloob @ianlancetaylor

I'm seeing this on linux/amd64 as well.

The hash it's expecting is the current commit and I think the hash it's finding is the commit I was on when I last ran all.bash. It looks like the archives in pkg/linux_amd64_race (or equivalent) aren't being updated by all.bash correctly. This is where I find the stale object header that the test is complaining about.

Reproducer:

git clone https://go.googlesource.com/go go.tmp
cd go.tmp/src
git checkout master^ && ./all.bash && git checkout master && ./all.bash

I had the same error building on linux/amd64. Applying https://golang.org/cl/16837 didn't help. I had to delete $GOROOT/pkg and rerun all.bash

This didn't fix the issue for me. My reproducer above still fails on the second all.bash with
