This error seems to be working on 7.0 and 7.2 (not tested yet on 7.1)

Can you make sure you are not somehow calling the file twice? use microtime() or other better methods to check if this is a valid bug

Pretty sure you're running it twice.

I found a problem in my program. This is not a PHP bug.

what i don't understand is why you did
not run the pretend 2 liner you posted as reproducer isolated and if it's only to be sure it shows the problem which it didn't
