Description:
------------
The following snippet results in a PDOException with message "SQLSTATE[HY000]: General error: 25 bind or column index out of range".

For some reasons, relatively similar queries work (for example, without the aggregation, as in: "SELECT * FROM (SELECT :value value FROM sqlite_master) my_table" or without the table as in "SELECT COUNT(*) expression FROM (SELECT :value value) my_table").



Test script:
---------------
<?php
$db = new PDO('sqlite:/tmp/sqlite.db');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$query = $db->prepare('SELECT COUNT(*) expression FROM (SELECT :value value FROM sqlite_master) my_table');
$query->execute(array(':value' => 'my_value'));
?>

hi Damien,

Do you use the bundled sqlite or a system version? If the latter, which version is it?

That's on Debian, so it is using the system library. I'm able to reproduce that behavior on a wide range of PHP and SQLite versions:

PHP 5.2.6-1+lenny9 -- SQLite 3.5.9 (external)
PHP 5.3.2-0.dotdeb.2 -- SQLite 3.6.21 (external)
PHP trunk -- SQLite 3.7.0.1 (bundled)

This seems to work properly with unnamed placeholders.

For named placeholders, it seems to only fail when the placeholder is part of a branch of the query that is deadcode, and could potentially be removed by the optimizer:

FAILS: SELECT SUM(1) expression FROM (SELECT :value value FROM sqlite_master) my_table
PASS: SELECT SUM(value) expression FROM (SELECT :value value FROM sqlite_master) my_table

I cannot reproduce this with current PHP 7.3 (Windows, bundled
libsqlite); can anybody else reproduce this with any of actively
supported PHP versions[1]?
