The bug usually occurs after calling opcache_reset() (but not always). So far I have been unable to prepare a script that would reliably reproduce it.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
I've attached a stack trace of a segmentation fault that occured to me on PHP 7.0.6. Perhaps it's related to a bug that was recently fixed in PHP 7.0.4? https://bugs.php.net/bug.php?id=71859
