为什么MSYS2 git尝试在无意义的目录中创建ORIG_HEAD.lock？

Question

我使用SourceTree委托MSYS2 git进行拉取。完整输出显示以下内容：

git -c diff.mnemonicprefix=false -c core.quotepath=false fetch upstream

git -c diff.mnemonicprefix=false -c core.quotepath=false pull --rebase upstream master
From https://github.com/metaeducation/ren-c
 * branch            master     -> FETCH_HEAD


First, rewinding head to replay your work on top of it...

fatal: Unable to create 'D:/dev/projects-open-source/ren-c_asampal/D:/dev/projects-open-source/ren-c_asampal/.git/ORIG_HEAD.lock': No such file or directory

Fast-forwarded HEAD to eb5e8acb29f315453d1ec58514acd8c25e1633eb.


git -c diff.mnemonicprefix=false -c core.quotepath=false submodule update --init --recursive
Completed successfully.

在创建锁定文件时，我应该在哪里查找伪造连接的原因？

我在Windows 10 64位下使用MSYS2 / MinGW-w64。
