-Summary: Creating associative array with long values in the key
fails under linux
Reported By: testuzer at hotmail dot com
Status: Verified
Bug Type: Arrays related
-Operating System: Linux - ubuntu
+Operating System: Linux 32bit - ubuntu
PHP Version: 5CVS, 6CVS (2008-11-28)
New Comment:
Can also confirm Linux -ubuntu 64bit works.
Actual result Linux 64bit (php 5.2.4):
--------------
Array
(
[3428599296] => 1
[3459455488] => 1
[3459616768] => 1
)
Obviously the 32bit os treats it as a signed 32bit value
and a 64bit os as a 64bit value..... so you get a positive
value. The array key handling is _only_ broken on linux 32bit.

Here is a simple test:
Reproduce code:
---------------
echo 0xcc5c4600;
var_dump( 0xcc5c4600 );
print_r( 0xcc5c4600 );
For both Windows and Linux - ubuntu the result is the same.
Actual result Windows 32bit:
--------------
3428599296
float(3428599296)
3428599296
Actual result Linux 32bit:
--------------
3428599296
float 3428599296
3428599296
So it is not a hex to long conversion problem.
Running the same array test using decimals and same values.
Reproduce code:
---------------
$test_array = array(
3428599296 => 1,
3459455488 => 1,
3459616768 => 1
);
print_r( $test_array );
Actual result Windows 32bit:
--------------
Array
(
[-866368000] => 1
[-835511808] => 1
[-835350528] => 1
)
Actual result Linux 32bit:
--------------
Array
(
[-2147483648] => 1
)

Is this really only happening with array indexes...? Either way, the
bug title isn't accurate.
If it's only with array indexes, it shouldn't be hexadecimal-related,
but would be coming from the simple (long) cast of any double value
(from "long values in the key") in zend_hash_*, resulting in "undefined
behavior."
But, are those values even correct before the array part gets
processed? e.g. does var_dump(0xcc5c4600) give 3428599296? If not, then
it's obviously not array-specific. :-) Hmm, I was just going to say, see
Bug #45068 for the possible cause (and
http://news.php.net/php.internals/40199), but I just noticed that you
marked that Bogus Jani? Cross-compiling isn't supported? Well, I guess
you're not doing that then when reproducing this... How about you, bug
reporter?

Same result with 32bit linux, this is with 64bit:
# php t.php
Array
(
[3428599296] => 1
[3459455488] => 1
[3459616768] => 1
)

Description:
------------
Creating associative array with long values in the key fails under
linux builds but work under windows.
Reproduce code:
---------------
$test_array = array(
0xcc5c4600 => 1,
0xce331a00 => 1,
0xce359000 => 1,
);
print_r( $test_array );
Expected result:
----------------
Array
(
[-866368000] => 1
[-835511808] => 1
[-835350528] => 1
)
Actual result:
--------------
Array
(
[-2147483648] => 1
)
