I guess that your error message is not matched due to the new behaviour
Changed from older versions is the regular expression handling. By default now all strings passed to expect() are treated as literals. To match a regular expression pass '-re' as a parameter in front of the pattern you want to match as a regexp. 
$object->expect(15, 'match me exactly','-re','match\s+me\s+exactly');

stated in the Expect docs, since you do not reset $err_flag if the prompt is matched.
