Dupe of #30. Happy for someone to have a go at fixing it, but all the array_push calls are a far bigger issue if you care about it failing nicely on out-of-memory.

Ah.. sorry, I checked the open issue and I didn't find anything.
This was a warning from our static analysis tool and I didn't investigate further.
I can give it a try to fix it, but I need approval from my company... and they are slooooooow.
