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.

The SegFault was coming from blackfire extension; when running console from Symfony application 2.7, `app/console` (without argument).

Regards.
 [2018-01-18 08:37 UTC] emir@php.net 
Can you please add a full list of extensions that you use? (php -m)
Do you happen to have Memcache extension installed? I have experienced the same segfault as well and I'm suspecting Memcache behaviour as well.

Is that still an issue with any of the actively supported PHP
versions[1]?  If so, does it only happen with blackfire enabled?
If so, have you reported that issue to them?
