Description:
------------
Team, 

I am upgrading our stack from PHP 5.6.x to 7.1.12 

The issue I am experiencing is a crash in the httpd child thread which then causes a restart of main httpd. 

Below is a windbg review. 

The load at the point of crash is a PHP api that reaches out to a mysql database for entries , massages the data and returns it as JSON. 

Please let me know what further details would be useful. 

Thanks!

Thanks for reviewing.

Is there any possibility that this feature will be merged to the 7.1.x Tree ? 

We have another component that is currently only in production builds for 7.1.x.

Appreciate the time,
Alan

Confirming issue is resolved in 7.2.0 

Would be great if it can be merged to 7.1.x Tree.

Many thanks for the checks! A backport into lower branches is unfortunately impossible, it was a huge patch that would breach BC.

Thanks.
