Look at the dates please. This was fixed after 5.5.8 was released which is why I asked you to try
the current code, not the 5.5.8 release. And it wasn't noticed because many people run with the
optimization_level set to 0 and it is also a weird edge-case script that triggers the bug.

> #66474 made my opcache stable again. Thank you

unconfirmed, see my commetn at that bugreport

i replaced the "opcache" folder from 5.5.8 tarball with the linked
master and from the first request on our asterisk-backend segfaults

how can it be that *two* following stable releases are that broken

Yes, we know it was the block_pass change as mentioned in previous comments here and https://bugs.php.net/bug.php?id=66474 has a
reproducing PHP code snippet. This issue was fixed, so if you want to help, make sure you are
building current HEAD (triple-check that you are replacing the newly .so correctly and restarting)
because everyone else who had this same issue is reporting it is solved in the current code. If you
can still make it crash with the current code, try to find the code snippet that does it and verify
that it doesn't crash with opcache.optimization_level=0

One shot - one kill ;)

This patch causes segfault:

http://git.php.net/?p=php-src.git;a=commit;h=d85ac7fb3f498455cfc1b051f8d48c9ba8ed8fdd

Going to test opcache 5.5.8 without this patch.

I`m going to add one patch per day to opcache starting with 5.5.6 as a base to pinpoint this
problem. I will post my results here.
