I'm running git 2.24.1 on Linux/WSL, and sometimes git fails with this error:
```
% git diff --cached
fatal: invalid commit position. commit-graph is likely corrupt
```
Usually that error goes away after I do a few more git operations, but
I haven't been able to discern a pattern yet. It's not always with
"diff", can be any git command as far as I can tell.
Perhaps it started after I enabled the commit-graph stuff:
```
[core]
editor = emacsclient -c -a \"\"
preloadindex = true
fscache = true
autocrlf = false
commitGraph = true
writeCommitGraph = true
```
In fact, when I turn off `commitGraph`, the error goes away. But as I
say, sometimes it goes away of its own accord.
Googling turns up almost nothing on this error. I have no idea if I've
done something wrong to corrupt the commit graph, or if it's a git
bug. If there's anything I can do to help debug it, I'd be happy to --
just let me know.
