[bug]fatal: fetch-pack: invalid index-pack output

[mingli zhang <zmlfoolishfish@gmail.com>]

HI,

At some point, I exec git pull/fetch/clone will got a fatal message:

```

fatal: fetch-pack: invalid index-pack output

```

I use git 2.36.1 on MacOS Monterey 12.3.1

```
git --version
04:51:36.776640 git.c:459 trace: built-in: git version
git version 2.36.1

```

Example:

```

zml@localhashdata postgres % git pull -r
04:53:33.553655 git.c:459 trace: built-in: git pull -r

```

I try to config memory or use git pull -r --depth 1, but didn’t help.

My git config is

```
[core]
packedGitLimit = 512m
packedGitWindowSize = 512m
compression = 0

[pack]
deltaCacheSize = 2047m
packSizeLimit = 2047m
windowMemory = 2047m
```

And the code dir permission is

```
drwxrwxrwx

```

Any suggestions ?

Regards,
Zhang Mingli
