Crash with ntea on USB memory sticks

["R. Diez" <rdiezmail-cygwin at yahoo dot de>]

Hi all:

I've seen a simple "ls -la" command crashing on a couple of computers, and I've managed to track it down to the combination of USB memory sticks (formatted with FAT) and CYGWIN option ntea. This is a small demo script:

  #!/bin/bash
  set -xv  # Trace on.

  # This is my CYGWIN, (default value + tty)
  export CYGWIN="winsymlinks nontea nontsec tty"
  /bin/ls -la /cygdrive/j

  # Change nontea -> ntea
  export CYGWIN="winsymlinks ntea   nontsec tty"
  # This crashes now.
  /bin/ls -la /cygdrive/j

The output of this script is as follows:

  $ ./test2.sh

  export CYGWIN="winsymlinks nontea nontsec tty"
  + export 'CYGWIN=winsymlinks nontea nontsec tty'
  + CYGWIN='winsymlinks nontea nontsec tty'
  /bin/ls -la /cygdrive/j
  + /bin/ls -la /cygdrive/j

  export CYGWIN="winsymlinks ntea   nontsec tty"
  + export 'CYGWIN=winsymlinks ntea   nontsec tty'
  + CYGWIN='winsymlinks ntea   nontsec tty'
  # This crashes now.
  /bin/ls -la /cygdrive/j
  + /bin/ls -la /cygdrive/j

File EA DATA. SF is there, I guess it has been created at some point in time by cygwin. I cannot open or delete it though. Actually, I would like to get rid of it, and I haven't find out yet how to do it!

I'm not on this list, so please copy me on any replies.

Thanks,
  Ruben
