Description:
------------
If I use diff method (doesn't matter on which variable),
usually (unfortunatelly not allways) round function returned some char (@, U, :, <, ...)

I was not able to realize cases. :(

Test script:
---------------
<?php

$t = new DateTime();
$s = new DateTime('2010-08-01');

$diff = $t->diff($s, true)->format('%d');
echo $diff ."\n";


$var = 98232923;
$mod = 82342;

$dur = round($var / $mod);
echo $dur;

Expected result:
----------------
2
1193

Actual result:
--------------
2
Ů

I copied old version of definition $t, should be:
$t = new DateTime('2010-08-03');

Does it happen only when the DateTime::diff method is used? I mean: never happened otherwise?

I have no expiriences with that in other cases. So, yes, it happens only when diff is used.

Can you try using VC9 please?

This bug is similar to another we have using vc6 crt but does not happen with VC9 (bug in the crt, not in php).

Yes, after your previous question I tried it and it was ok.
The most confusing thing on vc6 is the fact it sometimes goes right.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
