[php-maint] Bug#528600: Bug#528600: gforge: massmail.php segfault

[Niu Kun]

Hi Raphael,
Thank you for your reply.
But I failed to get a php5-dbg package on my system.
Here's my sources.list file
deb http://mirrors.kernel.org/debian/ testing main non-free contrib
deb-src http://mirrors.kernel.org/debian testing main non-free contrib
#deb http://www.emdebian.org/debian/ testing main
#deb-src http://www.emdebian.org/debian/ testing main
deb http://www.symfony-project.org/get debian/

#deb http://download.videolan.org/pub/videolan/debian sid main
deb http://oss.oracle.com/debian unstable main non-free

And I've run test.php file.
It works fine on my system.
Do you have any other hints?
Thanks again for your attention to my problem.

Regards,
Kun
