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 Stack trace: Frame        Function    Args 000FFFFABCC  001800614DE (0018028087A, 0018025A1B9, 00800010000, 000FFFF8B40) 000FFFFABCC  00180049249 (000FFFF9BC0, 000FFFFABCC, 00000000000, 00000000000) 000FFFFABCC  00180049282 (000FFFF9BC0, 00000000016, 00800010000, 3A445C3F3F5C) 000FFFFABCC  001800E23DC (000FFFFCBC0, 000FFFFCE00, 001800D2F78, 00000000000) 000FFFFCCD0  00180132725 (001800CB15C, 00000000000, 00000000000, 00000000000) 000FFFFCCD0  00180049873 (00000000000, 00000000000, 00000000000, 00000000000) 00000000000  00180048353 (00000000000, 00000000000, 00000000000, 00000000000) 000FFFFFFF0  00180048404 (00000000000, 00000000000, 00000000000, 00000000000) End of stack trace [04:42]D:\>pwd       0 [main] pwd (3192) D:\bin\pwd.exe: *** fatal error - add_item ("\??\D:", "/", ...) failed, errno 22 Stack trace: Frame        Function    Args 000FFFFABCC  001800614DE (0018028087A, 0018025A1B9, 00800010000, 000FFFF8B40) 000FFFFABCC  00180049249 (000FFFF9BC0, 000FFFFABCC, 00000000000, 00000000000) 000FFFFABCC  00180049282 (000FFFF9BC0, 00000000016, 00800010000, 3A445C3F3F5C) 000FFFFABCC  001800E23DC (000FFFFCBC0, 000FFFFCE00, 001800D2F78, 00000000000) 000FFFFCCD0  00180132725 (001800CB15C, 00000000000, 00000000000, 00000000000) 000FFFFCCD0  00180049873 (00000000000, 00000000000, 00000000000, 00000000000) 00000000000  00180048353 (00000000000, 00000000000, 00000000000, 00000000000) 000FFFFFFF0  00180048404 (00000000000, 00000000000, 00000000000, 00000000000) End of stack trace 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." in https://cygwin.com/ml/cygwin/2020-01/msg00129.html Thanks   Volker -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
