What a luck.  So just using the info class FileIdBothDirectoryInformation
plays havoc with TAS.  For the time being, I suggest to keep the above
setting disabled and use that tweaked Cygwin in your environment.

Here's one additional test I'd like to ask you to do for the sake of
Cygwin 1.7.  Please replace the FileBothDirectoryInformation with
FileDirectoryInformation and strace it again.  You'll suffer the crash,
but until then, does the NtQueryDirectoryFile return successfully?

That would be me.  I can add a special case for file systems choking on
FileIdBothDirectoryInformation.  But I fear the doughnuts will be cold
and stony when they arrive here...  Thanks for your patience to go
through this.
