Nope, built on same machine it's running. 32 bit machine and OS.

Are you cross-compiling for 32-bit, on a 64-bit system...?

Description:
------------
json_decode truncates numbers greater than 32 bit int 2147483647 on 32
bit system

Reproduce code:
---------------
<?

$json_encoded =
'{"test_id_small_int":12345,"test_id_maxint":2147483647,"test_id_maxint_plus_two":2147483649,"test_id_huge_int":80000000000}';

var_dump(json_decode($json_encoded));

?>


Expected result:
----------------
object(stdClass)#1 (4) {
  ["test_id_small_int"]=>
  int(12345)
  ["test_id_maxint"]=>
  int(2147483647)
  ["test_id_maxint_plus_two"]=>
  float(2147483649)
  ["test_id_huge_int"]=>
  float(80000000000)
}


or even strings instead of floats would work for me.

Actual result:
--------------
object(stdClass)#1 (4) {
  ["test_id_small_int"]=>
  int(12345)
  ["test_id_maxint"]=>
  int(2147483647)
  ["test_id_maxint_plus_two"]=>
  int(2147483647)
  ["test_id_huge_int"]=>
  int(2147483647)
}
