segfault help

["Tim Rupp" <caphrim007@xxxxxxxxx>]

Hi list,

I'm getting a segfault when I run (what I assume) is a very simple
script. I'm not sure if it's a php bug or a bug in the library I'm
using (MDB2) with PHP 5.2.5 via the cli. Everything seems to go fine
until it's time for the script to end. That's when it receives the seg
fault.

I have the following backtrace.

Program received signal SIGSEGV, Segmentation fault.

(gdb) quit
The program is running.  Exit anyway? (y or n) y


And it's occurring when I run this script



<?php

require 'lib/appDB.php';

$db = appDB::getInstance();
$count = 0;
while ($count < 10000) {
       $id = rand(30000,100000);
       $query = "insert into plugins (id) values ('$id')";
       $result = $db->exec($query);

       echo $count."\n";

       $count++;
}

exit;

?>


appDB is my own wrapper around this code



                       $options = array(
                               'debug_expanded_output' => true,
                               'quote_identifier' => true,
                       );

                       $db = MDB2::singleton("sqlite:///myfile", $options);

                       $db->setFetchMode(MDB2_FETCHMODE_ASSOC);
                       $db->setOption('persistent', false);


As shown above, I'm using sqlite. The database file and the folder
that the file is in are both writable by the user that I'm running the
script as.
Any help would be appreciated.

Thanks,
Tim
