So far I have been unable to prepare a script that would reliably reproduce it. Previous Comments: ------------------------------------------------------------------------ [2016-05-10 05:22:55] laruence@php.net 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. ------------------------------------------------------------------------ [2016-05-09 19:27:10] tom60 at op dot pl Description: ------------ I've attached a stack trace of a segmentation fault that occured to me on PHP 7.0.6.
