Description:
------------
Disabling ATTR_EMULATE_PREPARES produces a segmentation fault when using MySQL 8.0.

See test script.

Test setup:

Running a docker container for mysql (
docker run --rm -it -e MYSQL_ROOT_PASSWORD="test" -e MYSQL_DATABASE="systemA" mysql:8)

With a empty test table (at least id, updated field)

Running the script in a second container using php:7.4.15-cli or php:8.0.2-cli docker image for PHP and running "docker-php-ext-install mysqli pdo_mysql".

Then call the script and the SegFault happens.

gbd output:

Test script:
---------------
<?php
$pdo = new PDO(sprintf('mysql:dbname=%s;host=%s;charset=utf8', 'systemA', '172.17.0.4:3306'), 'root', 'test', [
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
    PDO::ATTR_TIMEOUT => 30,
    PDO::ATTR_EMULATE_PREPARES => false,
]);

$resultAssoc = $pdo->prepare("SELECT * FROM test WHERE :field >= :date ORDER BY :orderBy DESC LIMIT :offset, :limit");
$resultAssoc->execute([
    'field' => 'updated',
    'date' => (new DateTime('2020-02-01'))->format('Y-m-d H:i:s'),
    'orderBy' => 'id',
    'limit' => 1000,
    'offset' => 0,
]);
var_dump($resultAssoc->fetchAll(PDO::FETCH_ASSOC));


Expected result:
----------------
Empty array if nothing is in the DB.

Actual result:
--------------
Segmentation fault (core dumped)
