Package: bash
Version: 2.05b-26
Severity: normal
try the following commands:
echo $$
bash
echo $$
cat <<EOF >tmpfile
/usr/games/xxxxxxx
/usr/games/fortune
EOF
while read a b ; do echo ${a:5:-6} ; done <tmpfile
echo $$
what I see:
[EMAIL PROTECTED]:~$ echo $$
6406
[EMAIL PROTECTED]:~$ bash
[EMAIL PROTECTED]:~$ echo $$
6449
[EMAIL PROTECTED]:~$ cat <<EOF >tmpfile
> /usr/games/xxxxxxx
> /usr/games/fortune
> EOF
[EMAIL PROTECTED]:~$ while read a b ; do echo ${a:5:-6} ; done <tmpfile
bash: -6: substring expression < 0
[EMAIL PROTECTED]:~$ /usr/games/fortune
So many men; so little time.
[EMAIL PROTECTED]:~$ exit
[EMAIL PROTECTED]:~$ echo $$

it seems the failing brace expansion in the while loop leaves the
redirection from <1 open after the while loop terminates.
then when the contensts of the file are exhausted the shell terminates.
