Status: Feedback
Bug Type: Reproducible crash
Operating System: Mandrake Linux 8.2
PHP Version: 4.1.2
New Comment:
Derick,
I am now using RC1 from your page, and I still get the error.
Here are my compile options:
'./configure' '--prefix=/usr' '--with-mysql=/usr'
'--with-apxs=/usr/sbin/apxs'
'--enable-gd=/usr/lib/gd-1.8.4' '--enable-ftp'
I believe I've found what causes it. If I create a multi-dimensional
that has a sub-array at either
the beginning or end, the engine does not crash:
[root@anarchy.ma.cx]-[~]$ php -r 'error_reporting(E_ALL); $x =
array(array(),"c","b","a"); natsort($x);
print_r($x);';
Array
(
[0] => Array
(
)
[3] => a
[2] => b
[1] => c
)
The engine doesn't seggfault. However, if I create a multi-dimensional
array with a sub-array
anywhere but at the beginning or end, this happens:
[root@anarchy.ma.cx]-[~]$ php -r 'error_reporting(E_ALL); $x =
array("c",array(),"b","a"); natsort($x);
print_r($x);';
Array
(
[1] => Array
(
)
[3] => a
[2] => b
[0] => c
)
Segmentation fault

Weird, can't reproduce this at all:
$ php -r 'error_reporting(E_ALL); $x =
array("a",array("x","y"),"b");
natsort($x);'
Command line code(1) : Notice - Array to string conversion
Command line code(1) : Notice - Array to string conversion
Even with 4.1.2 on another machine no esegfault, just the warnings.

The problem arises when you attempt to natsort() a multi-dimensional
array, which in turn causes the engine
to segault.
[patrick@anarchy.ma.cx]-[~]$ echo '<? $x =
array("a",array("x","y"),"b"); natsort($x); ?>' |
php -q
Segmentation fault
This bug exists in both PHP-4.1.2 and the current PHP CVS as of
03/21/02.
