Unable to load dynamic library '/base/php_runtime/modules/curl.so'

[Roel Vermeulen via StackOverflow]

I'm using Google Cloud Platform's App Engine with PHP 5.5, and today I started receiving the following error in the logs:

PHP Warning:  PHP Startup: Unable to load dynamic library '/base/php_runtime/modules/curl.so' - /base/php_runtime/modules/curl.so: cannot open shared object file: No such file or directory in Unknown on line 0

It appears just after the following:

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

and it happens on different files (root directory, different JS files, etc.). I don't use cURL at all in the calls that are made. They are actually sometimes just simple JS files.

Google have been performing some kind of runtime upgrade which led to this issue.

Their known issues page says it has been happening since "10 May 2017, 12:00AM PDT".

It isn't on https://status.cloud.google.com/ yet, but it is in the Support portal.
