Release Status: release
Description:
If a function, f, declares a local readonly variable, v, using local -r, an
error occurs if f calls another function, g, that declares its own local
variable v (therefore shadowing v from f) and that assigns v to an array in
the same statement as the shadowing declaration.
g can, however, assign v to a scalar in a shadowing declaration.
g can also assign a shadowing v to an array, as long as it isn't assigned
in the same statement as the declaration.
Repeat-By:
function aaa() {
local x='1 2 3'
echo "aaa ${x}"
}
function bbb() {
local x
x=(4 5 6)
echo "bbb ${x[*]}"
}
function ccc() {
local x=(7 8 9)
echo "ccc ${x[*]}"
}
function ddd() {
local -r x='0'
echo "ddd ${x}"
aaa
bbb
ccc
}
ddd
# the above outputs the following:
ddd 0
aaa 1 2 3
bbb 4 5 6
bash: x: readonly variable
