I wasn't talking about the POSIX permissions, but about the Windows
ACL. In your current dir, what does `icacls .' print? Maybe that
gives a clue.

I just tried it myself with a local machine account and I can't
reproduce this. My pgid is "None" and the umask of 0022 leads to the
expected POSIX permissions:
vmbert8164+lcorinna@vmbert8164 ~
$ umask
0022
vmbert8164+lcorinna@vmbert8164 ~
$ touch bar
vmbert8164+lcorinna@vmbert8164 ~
$ ls -l
total 0
-rw-r--r-- 1 vmbert8164+lcorinna vmbert8164+None 0 May 5 16:41 bar

vmbert8164+lcorinna@vmbert8164 ~
$ chmod 400 bar
vmbert8164+lcorinna@vmbert8164 ~
$ ls -l bar
-r-------- 1 vmbert8164+lcorinna vmbert8164+None 0 May 5 16:41 bar
So I'd say it's not a generic issue but something in your environment.
It would be nice to know what that is, of course. Maybe there's some
security setting?!?
