Bug description: unserialize fails non-determenistic on large objects
I'm unserializing a large object using the following test script:
for ($i = 0; $i < 20; $i++)
{
echo "$i\n";
$ObjectToCreate = array();
if (!$fp = fopen('test.ser', 'r'))
return false;
$ObjectToCreate = unserialize(fread ($fp, filesize ('test.ser')));
fclose($fp);
}
I get the following output:

Repeatedly running the script produces different output each time with different
numbers of failures at different offsets. So far the lowest offset at which I have
had a problem is about 650000.
I can supply the 'test.ser' file on request but for obvious reasons do not wish to
include it in this error report!
