You'd get similar behavior for: ln -s . dot then trying to do a recursive listing of ./dot/** Without some form of symlink recursion detection (aka "have we seen the inode of this directory higher up in the tree?"), this will affect any symlink-to-directory hierarchy loop. Might be worth reporting it upstream to see if bash is willing to add an inode hash table to prevent infinite recursion on ** expansions across symlink loops, but as it is not a cygwin-specific issue, I'm not going to try and do anything about it downstream in the cygwin build of bash. --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --P6NMpAoEdIXiSdRomDuV2NvEjfAoTXUR0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJUwlTmAAoJEKeha0olJ0NqRxEH/jjyk/9gp/zR0RYfaeGZLEtw hkSK5BtPgLZXL9H46IQNy+Fk9mysMedzo81y9Bwenz1if9ReoYKfc0eYloZrX/lr P3hEx9hON9XLHsR0mltvTcm6uOCSoo0g+tFGDJK2gjWqeHlgWWWsLodjwpzynFlg vIYgYCA/TAtcYH09jW28ncTtHHQ3xLIwzG31duBGWh2KuNqpQDbXURnr1LjWbDEQ 4b82QhL0Sd5QR3JMmsUOLM++21DA4ON6oqTPvrvJ7Iz+yrE8w4KEfdZxvjJTbsWe fRH+gcmANBpBIVVF0frnEBDhrnk5UpWhdOLp9/UZgj/l4711280yBvUdxHr7LRs= =afuC -----END PGP SIGNATURE----- --P6NMpAoEdIXiSdRomDuV2NvEjfAoTXUR0--
