- Subject: Crash with ntea on USB memory sticks
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
/bin/ls: cannot access /cygdrive/j/EA DATA. SF: No such file or directory

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
