So, I am on PHP Version 7.2.19-0ubuntu0.18.04.1

Oh, and concerning your question: The docs at http://php.net/manual/en/serializable.serialize.php
say:
"Return Values: Returns the string representation of the object or NULL"
Although the return type declaration explicitly states "string" and not
"?string".
But this is probably not PHP7.1+ syntax anyways.

@felix: That's not quite the same bug, and something we can actually fix...
I wasn't aware that returning null from Serializable::serialize() is a thing. This was allowed
in https://github.com/php/php-src/commit/d77945ef78aead05a3adb6307ccedc12d0ca49ee,
but I'm wondering why... Do you happen to know?

I think this is the same bug, but quite simple to reproduce: https://3v4l.org/cTPe9
As soon as at least two serializable objects are pushed to a collection, it cannot be serialized
correctly anymore.
This is really bad news for any caching solution.
