I cannot reproduce the reported behavior. If you still experience
this misbehavior with any of the actively supported PHP
versions[1], please provide the Access database for download
somewhere on the Web.

Description:
------------
this problem was first noticed with 5.4.1; 5.4.0 works fine.
i am using PDO to read a ms access database with a memo field, at the command line interface. i
created a test database with one table and one field of type memo and one record. if the text in
that field is 255 chars of less, all is well. between 256 and 259 php returns scrambled data. at 260
it gives "zend mm heap corrupted". at 261 CLI blows up.
Test script:
---------------
<?
$dbq = "test.mdb";
$sql = "SELECT * FROM table1";
$pdo = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=$dbq;");
$result = $pdo->query($sql,PDO::FETCH_ASSOC);
foreach ($result as $row)
{
echo $row['COMMENT'] . "\n";
}
?>
Expected result:
----------------
the script should return whatever chars are in the memo field, up to 65536 max. instead it only
handles 255 chars as if it were a text field.
Actual result:
--------------
between 256 and 259 returns scrambled data. at 260 gives "zend mm heap corrupted". a 261
CLI blows up.
