Follow-up Comment #2, bug #46719 (project gnash):
I have created a new test which checks `GetVariable()` on undefined
(unassigned) and nonexistent variable within SWF version 5-8 under Flash
Player:
* Under SWF 5-6, `undefined` value translates to an empty string.
* Under SWF 7-8, `undefined` value translates to a string "undefined".
This is consistent to Adobe's documentation regarding `undefined` value
<http://help.adobe.com/en_US/AS2LCR/Flash_10.0/00000549.html>
and Gnash's `as_value::to_string()` documentation
<http://git.savannah.gnu.org/cgit/gnash.git/tree/libcore/as_value.h?id=15d61a804138737764689338c491c41f2cf59acf#n228>,
and also means that
current automated test must also be corrected so that expected value from
undefined/unassigned variable SWF6 is the same as SWF5.
variable-v5:
variable-v5's string_variable: type=string, value=Hello!
variable-v5's unassigned_variable: type=string, value=
variable-v5's nonexistent_variable: type=object, value=null
variable-v6:
variable-v6's string_variable: type=string, value=Hello!
variable-v6's unassigned_variable: type=string, value=
variable-v6's nonexistent_variable: type=object, value=null
variable-v7:
variable-v7's string_variable: type=string, value=Hello!
variable-v7's unassigned_variable: type=string, value=undefined
variable-v7's nonexistent_variable: type=object, value=null
variable-v8:
variable-v8's string_variable: type=string, value=Hello!
variable-v8's unassigned_variable: type=string, value=undefined
variable-v8's nonexistent_variable: type=object, value=null
