Could you please provide an example that doesn't require any external

Also please post what you expect and what you got when you execute the
reproduce code.

To reproduce the bug, use this script. Let 'TestDatabase' be any kind
of database, and let the table field 'Table'.'NullField' be any
database field that contains a NULL value.
<?php
try {
$DB = new COM("ADODB.Connection") or die("Cannot start ADO");
$DB->Open("DRIVER={SQL
Server};SERVER=SERVER\WEB;DATABASE=TestDatabase");
$RS = new COM("ADODB.Recordset");
$RS->Open("SELECT TEXT FROM Table", $DB);
echo $RS["NullField"];
} catch (Exception $e) {
echo $e->getTraceAsString() . "<br>";
echo $e->getMessage();
}
?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Description:
------------
zend_make_printable_zval:
Before returning with *use_copy=1, this function assumes that the
preceding code has successfully converted the value to a sting, and
therefore sets expr_copy->type = IS_STRING.
If the original value IS_OBJECT, this function relies on any 3rd party
cast handler to successfully return a string.
Some libraries have been observed to break this rule, and return a
value only initialized by ZVAL_NULL. This makes the system try to print
a string from a garbage pointer.
