Package: ircd-ratbox
Version: 2.2.8.dfsg-2
>From Ubuntu #313820
[https://bugs.launchpad.net/ubuntu/+source/ircd-ratbox/+bug/313820]:
Hi,
I'm trying to patch ircd-ratbox and use debuild to build the
resulting code into a package. When I do
that, I get a buffer overflow
for some reason. So I tried just building the source package itself
without any patches, and the resulting binary also segfaults:
r...@guest-laptop:/usr/src# /etc/init.d/ircd-ratbox start
* Starting ircd-ratbox ircd-ratbox [ OK ]
r...@guest-laptop:/usr/src# *** buffer overflow detected ***:
/usr/sbin/ircd-ratbox terminated

This is on Ubuntu Server 8.10, ircd-ratbox 2.2.8.dfsg, built and installed like
so:
cd /usr/src
apt-get source ircd-ratbox
cd ircd-ratbox-2.2.8.dfsg/
debuild -us -uc
cd ..
dpkg -i ./ircd-ratbox_2.2.8.dfsg-2_i386.deb
When I install ircd-ratbox with apt-get directly, it doesn't crash. Was it
built using a different
process?
kind regards,
