Bash Version: 3.1
Patch Level: 17
Release Status: release
Description:
An expansion like ${array[*]:index} renders empty elements as delete
(ASCII 127) characters. I have no idea of why this happens.
I am using bash 3.1, but I have tested bash 3.2.27 on an Ubuntu 7.04 machine
and it happens as well.
Repeat-By:
A simplified version of the code which caused the problem is:
IFS=/
file=/mnt/cdrom/RedHat/RPMS
echo "${file[*]:0:3}"
This will render "^?/mnt/cdrom/RedHat/RPMS".
It happens no matter the value of $IFS. For example:
i[0]=foo
i[1]=
i[2]=bar
i[3]=
echo "${i[*]:0}"
Will output "foo ^? bar ^?".
Strange...
