Bug description: Inconsistent behavior in array_pad() function.
Description:
------------
When a negative value of -12345678900 is passed for pad_size argument of
array_pad(), the function doesn't produce a warning in Linux environment
but a warning message is output on Windows. Whereas, when a positive value
of the above, i.e. 12345678900 is passed for pad_size argument, warning
message is output on both Linux and windows. This behavior is observed in
the testcase array_pad_variation2.phpt on Linux environment. Could you
explain the reason behind this inconsistent behavior.
This is applicable to PHP5.3 and PHP6 as well.
Reproduce code:
---------------
<?php
$arr = array(1);
var_dump( array_pad($arr, 12345678900, "hello") ); // warning generated
var_dump( array_pad($arr, -12345678900, "hello") ); // no warning
?>
Expected result:
----------------
Warning: array_pad(): You may only pad up to 1048576 elements at a time in
%s on line %d
bool(false)
Warning: array_pad(): You may only pad up to 1048576 elements at a time in
%s on line %d
bool(false)
Actual result:
--------------
Warning: array_pad(): You may only pad up to 1048576 elements at a time in
%s on line %d
bool(false)
array(1) {
[0]=>
int(1)
}
