Description:
------------
Changing the value of the ini setting sqlite.assoc_case to 
1 or 2 makes php crash.

Tested with PHP 4.4.2 w/ SQLite 1.0.3 -- libsqlite upgraded 
to version 2.8.17

Reproduce code:
---------------
<?php
if (is_file('test.db')) {
   unlink ('test.db');
}

ini_set('sqlite.assoc_case', 1); // or 2
$query = <<<END_OF_SQL
    CREATE TABLE authors (
        id INTEGER PRIMARY KEY,
        name VARCHAR(100),
        email VARCHAR(150)
    );
END_OF_SQL;

$db = sqlite_open('test.db');

sqlite_query($db, $query);

$query = 'PRAGMA table_info(authors)';

$result = sqlite_query($db, $query);
?>

Expected result:
----------------
Not a Segmentation fault anyway. I guess this is the same 
bug reported at http://bugs.php.net/bug.php?id=34884

Actual result:

Oops, my apologies 'cause this bug produces a signal 10 
(bus error) rather than a seg fault.

This will [likely] never be fixed. This PECL extension is no longer maintained, and I doubt ever will be. Instead use the well maintained sqlite extension that comes with the PHP sources.

The sqlite pecl page has been updated to reflect this.
