For what it's worth, I ran into this after a rebuild, and found that settin=
g:

[opcache]
opcache.optimization_level=3D0x2ef

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 l=
ife
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 th=
ere
are likely to be some issues. On the plus side, the performance gain is
incredible.
