[Bro] Potential bug with split_string_all?

[Earl Eiland]

I’ve been trying to use split_string_all in an event handler, but it’s throwing the error “unknown identifier split_string_all, at or near “split_string_all””.  In my debugging, I’ve ended up trying the example directly from the documentation (https://www.bro.org/sphinx/scripts/base/bif/strings.bif.bro.html#id-split_string):
   {
    local service_id = split_string_all("a-b--cd", /(\-)+/);
    }

Even this is throwing the error!  I’m a bro programming newbie, so my code may be broken.  If not, then is this a bug?

Please advise!
