Description:
------------
var_dump() doesn't show correct info about PHP_INT_MAX and PHP_INT_MIN constants on 64bit Windows

Test script:
---------------
<?php

echo PHP_INT_MAX, PHP_EOL;
echo PHP_INT_MIN, PHP_EOL;

var_dump(PHP_INT_MAX);
var_dump(PHP_INT_MIN);

Expected result:

-9223372036854775808
int(9223372036854775807)
int(-9223372036854775808)

Actual result:
--------------
9223372036854775807
-9223372036854775808
int(-1)
int(0)

It was a missing header issue. Now fixed.

Thanks for the report. Though, I cannot reproduce the behavior you describe? Do you compile with vc14 (lower are not supported for 7.0)? Please note also, that stdint.h shouldn't be included directly, see main/php_stdint.h.

Thanks.

Thanks for the info. Is that the same config you use for the custom build? Does it repro with -n?

Thanks.

you're correct, -n solves the issue, so it's about configuration

I figured out it's xdebug zend extension and it's default ini setting
xdebug.overload_var_dump = 2

It looks like it isn't just incorrect info about the constants.

$large_number = 2147483648;
var_dump($large_number);              // int -2147483648

$large_number = 2147483648;
var_dump($large_number);              // -2147483648

$large_number = 9223372036854775807;
var_dump($large_number);              // int -1

$large_number = 9223372036854775808;
var_dump($large_number);              // float 9.2233720368548E+18
