Oh, I see what you're getting at now. Sorry about that.

I still can't reproduce it, though.

Sorry but I'm misunderstanding what you are telling me. Why is the
number reduced to the 32bit limit? (2147483647)

Especially if you're saying the only way this could occur is with a
64bit OS?

As I stated in my last edit, wouldn't a 64bit OS return:
int(2147483648)

Revision: http://svn.php.net/viewvc/?view=revision&revision=296829
Log: Update to the integer type page to make it clearer how overflow
works on 32-
and 64-bit systems and what the critical thresholds are. Prompted by
bug #51274, although not an actual fix for it.

I can't really see any way this could occur other than your server
having a 64-bit install of Linux on it. What distribution is the
server running, what does "uname -m" output, and what does configure
say the host and target system types are?

(Side note: the manual could admittedly be a bit clearer on this;
although the fact integer size differs on different platforms is
mentioned, it might be useful if the Integer Overflow section
actually reiterated it. I'll see about updating it.)

64 bit ubuntu 10.04 PHP 5.3 SVN:
int(2147483647)
int(2147483648)

32 bit machine and OS PHP 5.2.10:
int(2147483647)
float(2147483648)

64bit machine, 32bit OS.
Also, wouldn't we expect a 64bit to return:

int(2147483647)
int(2147483648)
