Status: No Feedback
Bug Type: Reproducible crash
Operating System: *
PHP Version: 5.2.9
New Comment:
Same problem on Debian 5 32bit + php 5.2.6 when using recursive
call_user_func_array function.
The workaround is to use eval statement:
$object = 'foo';
$method = 'bar';
$args = array();//some arguments
$i=0;
$strArg='';
foreach ($args as $arg){
$varname = 'arg'.$i;
$$varname = $arg;
$strArg .= '$'.$varname.',';
$i++;
}
$strArg = substr($strArg,0,-1);
$cmd = '$_return = '.$object.'::'.$method.'('.$strArg.');';
eval($cmd);
//Enjoy :-)
return $_return;
Regards,
Cyril

I didn't know about Edit Submission. However, I did not open this bug,
I just had the same problem and tried to provide a script to
reproduce. Should I use that anyway?
Yes, the crash is there. I am getting:
[Fri Jan 08 17:55:49 2010] [notice] child pid 3534 exit signal
Segmentation fault (11)
in apache2's error log and the browser reports that it receives "Error
324 (net::ERR_EMPTY_RESPONSE): Unknown error."
php -n index.php ends with "Segmentation Fault".
If I include explicitly the class that otherwise autoload tries to
load, or if I do not use call_user_func_array, but a normal call, then
the crash is gone.

When editing you have to use the "Edit Submission" tab to re-open it.
Are you sure the script you provided is correct - it works for me, as
far as I can tell, on 5.2 and 5.3 while there is a warning for a missing
parameter:

I see the status has changed to "No Feedback". Is the script I provided
to reproduce not ok? I am sorry but I do not have a test environment
where I can try your snapshot.
