I can't reproduce this, but I can reproduce a similar problem.  I have
no idea, though, if I see different results for basically the same
problem as you do, because your report is lacking the information
requested on http://cygwin.com/problems.html 

What I see is a "Bad address" error message when trying to access
subdirectories of an UDF filesystem (a DVD), but I have no problem
accessing the root directory of a DVD for some reason.  This is on
XP SP2.

So, I can not track down your problem, but I could track down some
problem with DVDs.  It seems that the new NtQueryDirectoryFile flag
FileIdBothDirectoryInformation is not supported on UDF filesystems.  Oh
well.  Since I don't know if there are other restrictions of this new
call, I disabled it entirely, if the filesystem doesn't support useful
File IDs (inode numbers).
