Hi,
array_to_key() {
# Converts 1 2 3 -> 1,2,3, (comma at the end)
printf '%d,' "$@"
}
multi_store() {
local array_name="$1"; shift
local value="$1"; shift
if unset -v "$array_name"; then
declare -A $array_name
declare -- $array_name[$(array_to_key "$@")]="$value"
fi
}
multi_store CHESS_3D queen 2 2 5
(segfault)

Confirmed on linux and solaris. The intention was to create something
similar to famous 'upvar' function but dealing with a hash. I'm not 100%
sure it should work this way, but core dump seems to be a bit of an
overreaction :)
Thank you for bash, Chet!
