Feature detection should be more reliable.

;; Old GPLv2 BASH in macOSX does not support associative arrays.
(if-let ((bash (executable-find "bash")))
    (eq 0 (process-file
           bash nil nil nil
           "-c" "declare -A assoc_array")))

Even version check may be performed by shell

(if-let ((bash (executable-find "bash")))
    (eq 0 (process-file
           bash nil nil nil
           "-c" "[ ${BASH_VERSINFO[0]} -ge 4 ]")))
