Yes, ASLR it is, memory address randomization. I think on Linux the issue
were the same under circumstances.

There was a number of commits to opcache last week, I also merged them
into str_size_and_int64 branch. So the code base should be comparable. I
think the best way to handle it yet is using bugs.php.net, especially as
you mean the mainstream is unstable now as well. So if you can get a repro
case, or even just a BT, it'd be already the pretense to file a ticket.

The joy is almost untouched :), opcache is something we know to cause
issues in the mainstream too.
Thanks
