--- Comment #14 from Laurence 'GreenReaper' Parry <greenreaper at hotmail.com> ---
For what it's worth, I ran into this after a rebuild, and found that setting:

[opcache]
opcache.optimization_level=0x2ef

resolved the issue for me on a MediaWiki and Drupal installation (FreeBSD
10.4).

This removes passes 5 and 9 which perform block optimization and register
allocation, while leaving other optimizations intact. If this doesn't work for
you you could try setting it to 0 and then flipping bits like I did.

Obviously, this is not ideal, but as others have noted, 5.6 is kind of on life
support and the best solution is likely to be an orderly migration to 7.x
(ideally 7.1 or above) which will require testing of your application as there
are likely to be some issues. On the plus side, the performance gain is
incredible.
