Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Tried the same code on my Linux box at home (Fedora Core 2, first test
server I believe is Fedora 4), and it just gives a segmentation fault
instead. Tried the php5.1-200512091530 snapshot, and I get the same
results.

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
