Bash 3.2.57(1)-release "conditional binary operator expected"

Description

Running neofetch under Bash 3.2.57 results in "conditional binary operator expected" (line 1359 in 7.1.0 release: [[ $os =~ (AIX|IRIX) ]] && return'
(If this is expected behavior under Bash 3.2 then what is the correct minimum Bash version?)

PLATFORM INFO: SunOS 4.1.4 SPARC sun4

There seems to be no defined minimum version, but Bash 4.0-alpha contains the following release note:

b.  Fixed problems parsing arguments to the [[ command's =~ regular expression
    matching operator:  metacharacter and whitespace parsing.

You may wish to compile bash 4.x and see if the issue continues. I have confirmed neofetch works on bash 4.4 under Solaris 7, Intel Edition (though some lines aren't fetched correctly and the terminal is left in a corrupted state afterwards.)
