First, it's not a crash, but it is reproducable... 

Try this:
<html>
<body>
<? if ($a) { echo "<h1>$a</h1>"; } ?>
<form method=post>
  insert a big number here (12 digits beginning with a 5 or bigger):
  <input type="text" name="a" value="<?echo $a?>">
  <input type="submit" name="test" value="Test!">
</form>
</body>
</html>

Try it with 1234567890 and 12345678901
The second value prints 2147483647
It's a overflow problem.
I think that php should treat webinput as strings until
the variable is used.
I'm assuming that php tries to guess the variable type

Turns out beta 1 was used.
beta 3 or always set the type of form variables as string.
