PHP-fpm LOG 

[20-Jun-2018 18:37:29] WARNING: [pool www] child 99680 exited on signal 11 (SIGSEGV) after 187.014772 seconds from start

=========

The test script works as expected when running via php-cli , no matter imap enabled or not.

but with php-fpm or / laravel tinker. it breaks immediately with https.


=======

but if Starting php-fpm as root or staring laravel tinker as root . everything works.



Test script:
---------------
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, '1');
$url = 'https://www.google.com';
curl_setopt($ch, CURLOPT_URL, $url );
curl_exec($ch);

Expected result:
----------------
IMAP extension should not require any root permission to start php-fpm on macos in order not to break CURL with HTTPS.
