Edit report at https://bugs.php.net/bug.php?id=69524&edit=1 ID: 69524 Comment by: jarkkohyvarinen at hotmail dot com Reported by: js at xim dot de Summary: openssl-pkey-get-public() kill mysql(i) connection with ssl Status: Feedback Type: Bug Package: MySQLi related Operating System: Linux Debian PHP Version: 5.6.8 Block user comment: N Private report: N New Comment: If I call openssl_error_string() after openssl_pkey_get_public() the issue does not occur and queries through PDO object works fine. But if I put an invalid string to openssl_pkey_get_public the issue still occurs even if I call openssl_error_string.
