Just got another report to MSYS2 of this behavior, this time from a Gitlab
CI runner that is running as a service and trying to pipe output from
Microsoft cl.exe while running configure. This user reports that 3.3.4
with your "[PATCH v2] Cygwin: pipe: Avoid deadlock for non-cygwin writer."
applied to it does not solve the problem.

I can confirm the sample script hangs indeed if the script is
running as SYSTEM account. However, in my test, the patch solves
the issue.
It would be very helpfull if a simple github repository with
github actions, which can reproduce the issue, is provided.
In my environment with AD user account:
$ cmd.exe /c "type big_file" | :
The process tried to write to a nonexistent pipe.
$ cat big_file | :
*** starting debugger for pid NNN tid KKKKK
$ uname -a
CYGWIN_NT-10.0 ZZZZZZZ 3.3.4(0.341/5/3) 2022-01-31 19:35 x86_64 Cygwin
Remarks:
- no way to debug
- no error if run as administrator
Regards,
Roumen Petrov
