Bash Version: 4.4
Patch Level: 20
Release Status: release
Description:
Bash fails to correctly test for parameter to be unset or null when the
parameter is an array reference [*] or [@].
Repeat-By:
myvar[0]=
echo "${myvar[0]:+nonnull}"
<empty> -> OK
echo "${myvar[*]:+nonnull}"
nunnull -> not OK, because "${myvar[*]}" is null
echo "${myvar[@]:+nonnull}"
nunnull -> likewise not OK, because "${myvar[@]}" is null
