Mike,
thank you for your bug report. It will be fixed in
libmysql (see http://bugs.mysql.com/bug.php?id=8330)
Changed status to bogus (not a PHP bug)!

It's a bug in libmysql (cli_stmt_execute). I will check if
fix for will go in upcoming 4.1.10 release - otherwise I
will try to provide a workaround for mysqli.

Description:
------------
the tables contain two fields, each with 10000 rows where the names are
just 10-digit numbers
when I use the mysqli_stmt_bind_param, I get the 'memory could not be
"read"' error, when not used I get no error
Reproduce code:
---------------
<?php
$db = new mysqli("localhost","root","","test");
$tables =
array('t_0','t_1','t_2','t_3','t_5','t_all');
foreach($tables AS $table){
$stmt[$table] = $db->stmt_init();
$stmt[$table]->prepare("SELECT id, name FROM " . $table . " WHERE name
= ?");
$stmt[$table]->bind_param('i',$name);
}
for($i = 0;$i < 10;$i++){
$name = "";
for($j = 0;$j < 10;$j++){
$name .= rand(0,9);
}
foreach($tables AS $table){
$stmt[$table]->execute();
}
}
$db->close();
?>
Actual result:
--------------
'The instruction "0x00df82df" referenced memory at "0x0000000064". The
memory could not be "read".'
