pdo_sqlite segmentation fault

Description

The following code:

<?php
$db = Pdo\Sqlite::connect('sqlite::memory:');
$db->exec("CREATE TABLE t(x TEXT)");
$db->exec("INSERT INTO t VALUES ('b'),('a'),('c'),('d'),('e')");

$stmt = null;
$db->createCollation('evil', function ($a, $b) use (&$stmt) {
    $stmt->closeCursor();        
    return $a <=> $b;
});

$stmt = $db->prepare("SELECT x FROM t ORDER BY x COLLATE evil");
$stmt->execute();            

Resulted in this output:

Deprecated: Method PDO::sqliteCreateCollation() is deprecated since 8.5, use Pdo\Sqlite::createCollation() instead in /audit/repro/battery7/e7_06_collation_closecursor.php on line 8

issue の再現コードから始めて ext/pdo_sqlite/sqlite_statement.c:54 を調査し、その後、collation callback がカーソルを閉じる間に ext/pdo/pdo_stmt.c:456 を通る呼び出しを追跡します。完了の条件は、提供されたスクリプトが AddressSanitizer 下で segfault しなくなり、その動作が適切な回帰テストでカバーされることです。
