What did you do before the bug happened? (Steps to reproduce your issue)
Clean install of Git on Windows 10 using default options
git init --shared
echo x>x
echo y>y
git add -A
What did you expect to happen? (Expected behavior)
The two files are added with no errors
What happened instead? (Actual behavior)
error: unable to create temporary file: No such file or directory
error: y: failed to insert into database
error: unable to index file 'y'
fatal: adding files failed
What's different between what you expected and what actually happened?
The add command fails with an error 'unable to create temporary file'
Anything else you want to add:
If I omit --shared, there is no error
If there is only one file, there is no error
If the echo commands do not have characters, just adding a blank line, there is no error
If I turn off fscache, there is no error (git config --global core.fscache false)
All other filenames and contents also show the problem, for 2+ files
E.g. with files x,y,z,a,b, error happens on b - seems to be 2nd file in alphabetical order
The various GIT_TRACE_* options do not reveal anything useful, just normal setup up to trace: built-in: git add -A
Problem has existed for over a year (Google the 'unable to create...or directory' error and git)
Confirmed in git version 2.26.2.windows.1
Please review the rest of the bug report below.

Seeing this definitely makes me think this should be reported to the Git
for Windows project (https://github.com/git-for-windows/git) because
that's a nonstandard option that's specific to Windows. I don't think
anyone here (other, of course, than the Git for Windows folks) is
familiar with how that option works and since it isn't part of core Git
we wouldn't be able to fix it.

Thanks, duly reported: https://github.com/git-for-windows/git/issues/3110#issue-830551915
I note this bug does not occur in git version 2.9.3.windows.2 (2016) on Windows 10.0.18363.1316 with fscache
It seems to have existed since at least 2017: https://stackoverflow.com/a/44040893
