Description:
------------
Sorry I can't provide full test application cause it based on Yii 1.17/sqlite
But the php-cli error arises in next situation:

I have a simple yii1 migration script, that takes CSV-file and insert it in sqlite database via simpe model many times like this.

On the random loop with PHP 7.1.3 I always have SEGFAULT.

php.ini has no special limits and almost default. (memory_limit=-1)

With php 7.0 and php 5.6 everything is OK.

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.
