Comment 1 Daniel Kinzler 2012-10-16 10:45:38 UTC 
Looks like this will happen on all 32 bit systems

> Looks like this will happen on all 32 bit systems

It shouldn't be too big. That constant is equal to the default PHP_INT_MAX for 32 bit systems (according to the docs). You can try dumping PHP_INT_MAX to see if that server is different.
Comment 3 Daniel Kinzler 2012-10-16 16:31:02 UTC 
@Aaron: Which documentation? You can't represent the number 2147483648 with 31 bits (bit 32 is the sign). The max would be 2147483647. Indeed, print PHP_INT_MAX returns 2147483647 on a 32 bit system.

Anyway... why not just use the constant PHP_INT_MAX? Because it's too large on a 64 bit system?...

Actually I see the problem. I was looking at line 281, which uses 2147483647, but there is another line that uses 2147483648 for some reason.
