Hi,

I know this isn't the proper channel for a bugreport, but I think this
segfault will require a very simple fix and I hope this could be fixed
before 5.0.4 is released (so I'm posting this because of the time factor).

This code segfaults (PHP 5.0.3):

<?
$server = stream_socket_server("tcp://0.0.0.0:12345");
$client = stream_socket_accept($server, 3, $peername);
?>

while this doesn't:

<?
$server = stream_socket_server("tcp://0.0.0.0:12345");
$client = stream_socket_accept($server, 3);
?>

So the problem is obviously in the feedback variable "peername". I was
hoping this might be fixed before 5.0.4 rolls out.

Thanks,

Ron Korving

Did I miss something or there wasn't even RC1 yet?

Please, fill a bug-report and don't forget to include backtrace.
Btw, I can't reproduce it with current CVS.

I don't know exactly when PHP 5.0.4 will be released, but I understood from
Andi's posts that he wanted to get 5.0.4 out pretty soon.

Could you tell me how I can create a backtrace? (I use a precompiled PHP
5.0.3, so I'm not sure if I can do this with my software). I noticed there
are backtrace php functions, but how can I call a function after php
segfaults?

Thanks,

Ron

Read the instructions that our bugreport form refers to:
http://bugs.php.net/bugs-generating-backtrace.php

Unfortunately right now I don't have the time to do this. I posted a
bugreport ( http://bugs.php.net/31633 ). Maybe I can try to add a backtrace
later.

Thank you,

Ron

Hi Ron,

I think, I fixed this bug week or two ago.
Did you tested it with shapshot from http://snaps.php.net?

Thanks. Dmitry.

I think I fixed this problem up to a month ago in HEAD.
