Stop smuggling guns and narcotics dammit! You should be clean after that.

Not enough info to diagnose your problem.
If you can configure your system to make a core dump and provide the exact version of the program we can probably figure out what it is.

Still need debian version to reproduce it… 6.x? 7.x? 8.x?
Still need CDDA version

Same problem here on ubuntu 2.6.32-38-generic. I suspect gcc version (gcc (Ubuntu 4.4.3-4ubuntu5.1) 4.4.3) as i can play from that same ubuntu installation but chrooting to an Archlinux (gcc (GCC) 4.9.1) i installed on a usb key. I have some graphics missing though (objects not showing: it seems that an image file for those objects/monsters couldnt be found).
I compiled the git version (2014-08-09 17:55) with SDL.

Turns out that the git version works in the Arch USB key but not the compiled versions (SDL and ncurses). My CPU is an old “AMD Athlon™ XP 2400+”. Might it be due to the fact that it doesnt support SSE2 and above? I have similar problems with other compiled packages (i guess they are compiled with SSE2+ flags enabled).

The only thing that comes to mind is that perhaps we’re building for 64 bit architecture now. As far as I know we’re not using any options that restrict what systems it can run on.

Output of ‘file’ command on cataclysm executable:

It’s a 32bit executable.
