I'm using 1.2.4.

Where do you call a function from? In my configuration it is called from
filter:

function check_community (clist c)
pair set wrong;
{
        wrong = [
                (0,0)..(0,25371),
                (0,25373)..(0,31209),
                (0,31211)..(31209,65535),
                (31210,0)..(31210,25371),
                (31210,25373)..(31210,65535),
                (31211,0)..(65535,65281),
                (65535,65283)..(65535,65535)
        ];
        c = delete(c,wrong);
        print c;
}

# ----------------------------------------------------------------------------
filter flt_itcons_i  
prefix set plist;
{
        check_community(bgp_community);
        plist = [
                194.247.174.0/23,
                91.200.192.0/22,
                109.68.40.0/21,
                91.197.128.0/24,
                91.197.129.0/24,
                91.197.131.0/24,
                91.197.128.0/23
        ];
        if net ~ plist then accept; else reject;
}

bird still reports error: Sep  7 13:45:58 crete bird: filters, line 37: Can't add/delete non-pair

Also I tried fillowing config:
function check_community ()
pair set wrong;
{
        wrong = [
                (0,0)..(0,25371),
                (0,25373)..(0,31209),
                (0,31211)..(31209,65535),
                (31210,0)..(31210,25371),
                (31210,25373)..(31210,65535),
                (31211,0)..(65535,65281),
                (65535,65283)..(65535,65535)
        ];
        bgp_community.delete(wrong);
        print bgp_community;
}

filter flt_itcons_i
prefix set plist;
{
        check_community();
        plist = [
                194.247.174.0/23,
                91.200.192.0/22,
                109.68.40.0/21,
                91.197.128.0/24,
                91.197.129.0/24,
                91.197.131.0/24,
                91.197.128.0/23
        ];
        if net ~ plist then accept; else reject;
}

Error is the same: Sep  7 13:45:58 crete bird: filters, line 37: Can't add/delete non-pair
