Bug description: PHP segfaults on exit() with PDO prepared statements
Description:
------------
[Note: This bug is against PHP 5.1.6, but the bug interface only offers
5.1.5.]
The code below makes PHP segfault at the time that exit() is called. This
happens with both CLI and Apache 2 (prefork). I'm using MySQL 4.1.11.
If the return value of prepare() is not assigned to a variable, the script
does not crash. Also it does not crash when omitting the exit() call.
Reproduce code:
---------------
<?php
class SomeClass {
public function doSomething($id) {
$dsn = "mysql:host=localhost;dbname=weblog";
$db = new PDO($dsn, "weblog", "weblog");
$stm = $db->prepare("UPDATE entry SET id = ?");
exit();
}
}
$obj = new SomeClass;
$obj->doSomething(1);
Expected result:
----------------
No crash.
Actual result:
--------------
