mt_rand not at all random?

Hi,

The following script:

<?php echo mt_rand();?>

always outputs "1755202938" on my machine. I'm running PHP 4.2.3 under
Windows XP.

According to the docs:
"As of PHP 4.2.0, there is no need to seed the random number generator with
srand() or mt_srand() as this is now done automatically."

So why the non-random behavior?

It might be a bug in your release. I've tested under 4.2.2 (Red Hat Linux)
and values are always different. Do you get random values if you do seed
the generator?

It could also be that it doesn't work this way under Windows but docs do
not mention it :-?

Follow-up for anyone who runs into this same problem:

I upgraded to PHP 4.2.9 and the bug seems to be fixed.
