Can someone merge `Catchable "Call to a member function bar() on a non-object"`?

Hi,

two weeks ago, the RFC `Catchable "Call to a member function bar() on a
non-object"` was accepted by a vote. I don't have commit access to php-src/Zend,
so I can't commit this myself. Back from my summer vacation, I thought I'd whip
up this email (after bringing the pull request up-to-date and making it
mergeable once again) and ask whether someone here can review[1] and then merge
the PR https://github.com/php/php-src/pull/647?

Thanks in advance!
