Hi
I always installed my Cygwin environment on the root of a dedicated
drive (for example D:)
instead of the Setup.exe suggested subdirectory (for example D:\cygwin)
I recently upgraded my Cygwin system from cygwin1.dll (version 3.0.9) to
the latest 3.1.2-1 package.
Now whenever I call an executable linked with this dll I get the
following stack trace:
[04:38]D:\>Cygwin.bat
0 [main] bash (5368) D:\bin\bash.exe: *** fatal error - add_item
("\??\D:", "/", ...) failed, errno 22

The only mention of "\\??\\D:" seems to come from the
""HKEY_CURRENT_USER\Software\Cygwin\Installations"
registry entry (see below)
I then tried new base installations under "D:\cygwin", "C:\" and
"C:\cygwin":
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Cygwin\Installations]
"8aa36a1fe80b21a1"="\\??\\D:" <=== Broken
"c5e39b7a9d22bafb"="\\??\\C:\\cygwin" <=== OK
"1720b01b097bf4fc"="\\??\\D:\\cygwin" <=== OK
"2af6b8d6450bff37"="\\??\\C:" <=== Broken
It looks like installations directly to the root of a drive DO NOT work
anymore, although the Cygwin
installer still allows it (with a warning).
This all seems to be related to a patch mentioned in
https://cygwin.com/ml/cygwin/2019-09/msg00255.html
My big problem is: ALL of my Cygwin installations on different systems
now will break
during upgrade because of the initial Root-Drive install. Also the rest
of my ecosystem
assumes this Root-Drive install and its a nightmare to fix.
Any chance this type of installation can be supported again?
I found a mention of Ken Brown "I think I see how to fix this. I'll
submit a patch within the next few days."
