Package: php5-dev
Version: 5.6.12+dfsg-0+deb8u1
Severity: important

Dear Maintainer,

Seems integer overflow is bogus on x32 arch

According to php doc 

> If PHP encounters a number beyond the bounds of the integer type, it will
> be interpreted as a float instead. Also, an operation which results in a
> number beyond the bounds of the integer type will return a float instead.


This works fine on i386

php -r 'echo("Number: " . (2147483647 + 1) . "\n");'
Number: 2147483648

The same code on x32

php -r 'echo("Number: " . (2147483647 + 1) . "\n");'
Number: -2147483648
