Too many level of symbolic links (still have problem with sbmfs network drives)

[Philippe Debanne]

Hello Cygwin list,

Since updating my Cygwin installation to the latest version, I am having 
the problem of  "Too many levels of symbolic links" on certain network 
drives, that was reported in other threads.  I tried replacing the  
'cygwin1.dll' with the snapshots from 2022-02-17 and 2022-03-01 
(x86_64).  This did fix the link to one of the network drives, but not 
others.

The mount command in my case gives :

$ mount
D:/cygwin64/bin on /usr/bin type ntfs (binary,auto)
D:/cygwin64/lib on /usr/lib type ntfs (binary,auto)
D:/cygwin64 on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto)
L: on /cygdrive/l type cifs (binary,posix=0,user,noumount,auto)
V: on /cygdrive/v type smbfs (binary,posix=0,user,noumount,auto)
W: on /cygdrive/w type smbfs (binary,posix=0,user,noumount,auto)
X: on /cygdrive/x type smbfs (binary,posix=0,user,noumount,auto)
Y: on /cygdrive/y type smbfs (binary,posix=0,user,noumount,auto)
Z: on /cygdrive/z type smbfs (binary,posix=0,user,noumount,auto)

No problem with the local drives, and I can now go to the X: drive 
thanks to the recent snapshot.  But not other 'smbfs' ones :

$ cd Z:
-bash: cd: Z:: Too many levels of symbolic links

Any ideas what could be wrong ?  It seems to be limited to certain SAMBA 
shared drives.
