PHP version: 5.1.1
PHP Bug Type: PDO related
Bug description: PDO crash
Description:
------------
PHP crashes on the following code. Changing the second named marker from
:foo1 to :foo2 fixes the crash, which made me think it had to do with
duplicate names. However, removing the where clause (leaving both name
markers :foo1) also eliminates the crash, though the statement gets an
error code of "HY093" (no full message).
Reproduce code:
---------------
<?php
$db = new PDO("pgsql:host=localhost dbname=name user=user
password=password");
$stmt = $db->prepare("UPDATE test SET foo1 = :foo1, foo2 = :foo1 WHERE
foo1 = :id");
$stmt->bindParam(':foo1', $foo1);
$stmt->bindParam(':foo2', $foo2);
$stmt->bindParam(':id', $id);
$foo1 = "foo";
$foo2 = "foo";
$id = "foo";
var_dump($stmt->errorInfo());
$stmt->execute();
?>
Expected result:
----------------
An error message of some kind if duplicate names aren't allowed, but
certainly not a memory dump.
Actual result:
--------------
*** glibc detected *** php: free(): invalid next size (fast): 0x09980018
***
Followed by a backtrace and memory dump
