Bug description: zend_mm_heap corrupted
Description:
------------
I'm working with WDDX extension, used to make RPC between two computers,
using classes to make wrapper. I have 3 basic scripts, one is the client,
other is the server and other contains the classes that contains the
scripts that interact with WDDX.
When I try to simulate the client and the server over the same machine, I
get the error zend_mm_heap corrupted in apache. When I ran the scripts in
separate machines, it works OK.
I have PHP 5.2.4, I had tried to run with PHP 5.2.3 but I got the same
error. I have
Apache/2.2.4 (Win32) mod_autoindex_color PHP/5.2.4. I try to run a debug
with php, but I got it only with apache process.
the error in apache log is
[Sun Sep 30 11:20:52 2007] [notice] Child 3156: Starting thread to listen
on port 80.
zend_mm_heap corrupted
Error in my_thread_global_end(): 51 threads didn't exit
[Sun Sep 30 19:08:19 2007] [notice] Parent: child process exited with
status 1 -- Restarting.
[Sun Sep 30 19:08:38 2007] [notice] Apache/2.2.4 (Win32)
mod_autoindex_color PHP/5.2.4 configured -- resuming normal operations
Reproduce code:
---------------
function creaPaquete($datos)
{
$packet_id = wddx_packet_start("Llamada Remota WDDX");
if (is_array($datos)) { //verVar($datos);
foreach($datos as $key => $data){
//create a var whith the name of the content
of $key
$$key = $data;
wddx_add_vars($packet_id,$key);
}
}
else {
wddx_add_vars($packet_id, "datos");
}
$paquete = wddx_packet_end($packet_id);// verVar($paquete);
$paquete = urlencode($paquete);
return $paquete;
}
Expected result:
----------------
this function packs the data to send over the network using CURL. The code
is too large to include here, and I'm not have a web site permanently
connected.
Actual result:
