I don't have a copy of 3.2.4 to verify my suspicion on, but I think the "~" 
character in the output was introduced after version 3.2.4.

Thus, If you replace the tilde's with some place-holder variables the syntax 
error should go away.

        [foobar1,foobar2,foobar3, fmt_words] =  regexp (formatstr, "[^\\s]+");
