Possible segfault with `git clone --mirror`

Possible segfault with `git clone --mirror`

[Kostya M]

Git 2.31.1, reproduced on Ubuntu 20.04.01, and Arch Linux.

`git clone -c core.askPass=true --mirror --quiet --
https://github.com/kostya/myhtml.git myhtml`
Segmentation fault (core dumped)

If i remove --mirror argument, it works.
This command generated by crystal language package manager called shards.

Not reproducible.

You may want to check if it's your config or filesystem first?

If I were you, I would run something like this to see if it works:
(Maybe with GIT_TRACE2=1 removed in first run to see if it's your config)

	HOME=/tmp/not-exist XDG_CONFIG_HOME=/tmp/not-exist GIT_TRACE2=1 \
		/usr/bin/git clone -c core.askPass=true --mirror --quiet -- \
		https://github.com/kostya/myhtml.git myhtml

Yes, adding `HOME=/tmp/not-exist` fix this.

my ~/.gitconfig is (maybe it have outdated options, it was generated long ago):

[color]
  status = auto
  branch = auto
  diff   = auto

[core]
  symlinks = false
  autocrlf = false
  repositoryformatversion = 0
  filemode = false
  bare = false
  logallrefupdates = true
  symlinks = false
  ignorecase = true
  quotepath = false
  pager = less
  editor = "vim"

[pack]
  packSizeLimit = 2g

[apply]
  whitespace = nowarn

[i18n]

That's probably the one.  There's a related fix in master:
