Bash Version: 3.1
Patch Level: 17
Release Status: release

Description:

If the IFS does not contain a blank, copying an array using
("address@hidden") works, but creating a sub-array using
("address@hidden:offset:length}") does not work.

Repeat-By:

IFS=$'\n'
a=(A B C D)
b=("address@hidden")
echo "address@hidden", "address@hidden"  # 4, A B C D -- OK
b=("address@hidden:2}")
echo "address@hidden", "address@hidden"  # 1, C D -- bug, should be 2, C D
