Description:
------------
simple script coredumps

the configure parameters are

./configure --disable-cgi --prefix=/usr/local/php5.1-debug --with-pdo-pgsql --with-gd --with-gd-native-ttf --with-jpeg-dir --with-png-dir --with-xpm-dir --with-zlib --with-pgsql --with-freetype-dir --enable-debug


the coredump is

Reproduce code:
---------------
<?
$dbh = new PDO('pgsql:dbname=test;host=localhost', 'xxxx', 'xxxx');

$stmt = $dbh->prepare('SELECT * FROM child');
$stmt->bindValue(':test', 1, PDO::PARAM_INT);
$stmt->execute();
?>

Expected result:
----------------
just nothing special - not to coredump, or some kind of error to indicate that could not bind ":test"

Actual result:
--------------
ce@ce:~/tmp$ /usr/local/php5.1-debug/bin/php test.php
Segmentation fault (core dumped)
