19:04:44 UTC 2008 i686 GNU/Linux
Machine Type: i686-pc-linux-gnu
Bash Version: 4.0
Patch Level: 33
Release Status: release
Description:
The expansion "${@:0:n}" should be $0 followed by the first
n-1 positional parameters, but is instead $0 followed by
the first n-2 positional parameters. This behavior is different
from ksh93 and seems nonsensical and unintentional.
Repeat-By:
set -- a b c d
echo "${@:0:3}" # prints "bash a"; should be "bash a b"
Fix:
Apply the following patch. The important effects are on
the behaviour of the following loop (params && i < end),
which without the patch is iterating one time too few.
