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 (form=
atted 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=3D"winsymlinks nontea nontsec tty"
  /bin/ls -la /cygdrive/j

  # Change nontea -> ntea
  export CYGWIN=3D"winsymlinks ntea   nontsec tty"
  # This crashes now.
  /bin/ls -la /cygdrive/j

The output of this script is as follows:

  $ ./test2.sh

  export CYGWIN=3D"winsymlinks nontea nontsec tty"
  + export 'CYGWIN=3Dwinsymlinks nontea nontsec tty'
  + CYGWIN=3D'winsymlinks nontea nontsec tty'
  /bin/ls -la /cygdrive/j
  + /bin/ls -la /cygdrive/j
  /bin/ls: cannot access /cygdrive/j/EA DATA. SF: No such file or directory

  # This crashes now.

File EA DATA. SF is there, I guess it has been created at some point in tim=
e by cygwin. I cannot open or delete it though. Actually, I would like to g=
et 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
