Most probably not, but it's one that affects us. Curiosly, our own code contains zillions of things like "Exception $e". We never observed logs from these but what happens on a regular basis is like

$f = new Foo();
$f->bar();

Results in
[E_NOTICE] Undefined variable: f
+
Call to a member function bar() on null

Yes, I am serious :(

Can you add the 2 php version to travis?
So that we can see if it really fails or you have some custom setting in your php version.

And can you please change than all of the places where something like this exists

If you take a look on symfony code, they have many single-char names for functions

And im not against it, to change the single-chars to a normal name

@prisis Adding more php versions to travis won't prove anything unfortunately. We cannot reproduce that in a deterministic way. We observe that bug only in long running programs after an indefinite amount of time.
We never observed that in PHPFPM as this creates a PHP runtime for every single request. I am 99.9% sure it is a bug in the PHP memory management.
WHEN we observe that, ALL single-char vars (at least in certain places) cause that problem from the moment of the first occurence until the process is restarted.

Btw.: I opened a PHP issue for that https://bugs.php.net/bug.php?id=75710&thanks=4

On the top of my head, this is the only place we use a single char var like this.

I’m also not sure of adding these PHP versions to Travis. Travis does not even support all patch versions.

@Nyholm Then I'd be happy about a merge :) Actually it's not a big deal, right?

Thank you.
I'll do a search to see if we have anymore of these one char vars
