argus reliably crashes on startup on 24.04

[Gavin Atkinson]

Argus reliably crashes immediately on startup on 24.04 for anything other than "argus -h".

root@test2:~# argus -i lo
*** buffer overflow detected ***: terminated
Aborted (core dumped)

root@test2:~# argus -X
*** buffer overflow detected ***: terminated
Aborted (core dumped)

This is "argus-server/noble,now 2:3.0.8.2-2.3build1 amd64"

"argus-server/jammy,now 2:3.0.8.2-2.1 amd64" from 22.04 starts up fine on both 22.04 and when manually installed on 24.04 (though has another bug meaning it's not usable on either - see bug 2102103 for the fix).

Status changed to 'Confirmed' because the bug affects multiple users.

This seems to be related to source fortification.
If I build the argus binary myself it works with
export CFLAGS=-D_FORTIFY_SOURCE=1 ./configure
export CFLAGS=-D_FORTIFY_SOURCE=2 ./configure
but if I do
export CFLAGS=-D_FORTIFY_SOURCE=2 ./configure
then I get the same error as in argus-server 2:3.0.8.2-2.3build1
