New Comment:
Thanks very much to you all for looking into this issue.
So do you think this is a PHP 7 bug or does the Drupal Views code need to be adjusted for PHP 7?
The error appears only under PHP 7.
@nikic@php.net, would you please explain this part from your comment:
"t's because there is an object with a dynamic properties HT, which contains and INDIRECT
to and UNDEF" ..
The View's class definition is here (expand View source item in page):
https://api.drupal.org/api/views/includes%21view.inc/7
The ctools_object_cache code (where the view's object gets serialized):
http://www.drupalcontrib.org/api/drupal/contributions%21ctools%21includes%21object-cache.inc/7
Thanks.

Here we go: https://3v4l.org/KiLqN
class A { public $b; }
$a = new A;
var_dump($a); // force properties HT
unset($a->b);
var_dump(serialize($a));
Results in "O:1:"A":1:{}" while it should be "O:1:"A":0:{}".

If I were to venture a guess, it's because there is an object with a dynamic properties HT,
which contains and INDIRECT to and UNDEF. The hashtable count will then include the UNDEF, but it
will not be actually present in the properties list.

For some reason the serialized string is corrupt. Both
view_display objects declare to have 8 properties, but they only
have 7. The views_display object declares to have 55 properties,
but it has only 51. Fixing these issues manually lets
unserialize() succeed, see <https://3v4l.org/Pvr91>.
So obviously, this is not an issue with unserialize(), but rather
with serialize(). It would be helpful to have a minimal reproduce
script.

I tried to unserialize your string <https://3v4l.org/EYtah>, but failed in all php version,
including php5.6. Is there any invisible characters in your original string?

More information:
The error I get is this:
Notice: unserialize(): Error at offset 2101 of 3558 bytes in ***
Under HHVM I get:
Notice: Unable to unserialize: [{the string}]. Expected ':' but got 's'. in ***
The strange thing that there is no : in the specified position.
Allow me to attach the string to be unserialized and that causes the problem:
