[Linux] CTD when opening/closing tabs

bucaneer · Jan 15, 2013

I've experienced three CTDs in a short play session - one happened when closing the Factions tab, another when switching from Factions to Intrigue, and the third when opening Character tab. There is no terminal output and the only thing that seems sort of relevant to the crashes in game logs is this repeated line from error.log:

Code:

[/var/lib/jenkins/jenkins-tmp/jenkins-tmp/workspace/CK2-Release-Linux/clausewitzII/clausewitzlib/sound.cpp:232]: Sound factions_view not found.

Although it appeared in the log when the crash occurred while opening Character tab as well, so I'd doubt that's the cause.

Systemd managed to catch the core dumps of all crashes - I've uploaded the first one here and can do the same for the others if it is at all useful.

I'm using Arch Linux 64bit, 3.3.7-ck kernel, nVidia GTX 650 Ti graphics card with 310.19 drivers.

As far as I'm aware, both the Steam Linux client and the CK2 Linux edition have not formally been released as yet. Are you finding otherwise?

bucaneer · Jan 15, 2013

The Linux Steam client is currently in open beta, and CK2 has been released on it today - there was confirmation from Doomdark that this would happen, the game is listed in the Linux section of Steam store, and the CK2 page there lists Linux system requirements. At least it looks pretty official.

Steam for Linux was officially released some weeks ago, and CK2 was today.

I can also reproduce this on 64-bit Arch Linux, kernel3.6.11 with a Nvidia GTX 550 Ti and 310.19 drivers.

An apparently 100% reproducible version of the crash is going to the introductory tutorial and clicking on the realm view shield icon when prompted, as reported in the Steam forums (here and here)

Thank you for your reports, we'll look into the crashes today

I have the same problem since I bought the Republic DLC, before that it was working fine.

ArchLinux with kernel 3.6.11 64bit, Nvidia 310M with 310.19 drivers using Bumblebee.

Tegus:

If you add a signal handler to SIGSEGV, you can obtain stacktrace for all of these crashes, instead of trying to dig through things yourself.

#ifndef WIN32
/* This is for obtaining a stacktrace */
void traphandler(int sig)
{
void *array[50];
size_t size;

/* get void*'s for all entries on the stack */
size = backtrace(array, 50);

/* print out all the frames to stderr */
fprintf(stderr, "Error: signal %d:\n", sig);
backtrace_symbols_fd(array, size, 2);
exit(1);
}
#endif

Install the signal handler using (preferably early in main):

#ifndef WIN32
/* Install signal handler */
signal(SIGSEGV, traphandler);
#endif

Note, there are some caveats doing this, check the backtrace_symbols_fd/backtrace man page for details.

I also have this problem with segfault semi-randomly when clicking one of the icons in the top left corner. Sometimes it happens in the beginning of the game and some times I can play for a while, but it's always when I click one of those buttons. Here's a backtrace:

When a tutorial crashes I get the following backtrace:

#13 0x08a0ad4e in CApplication::Run() ()
#14 0x0874c402 in main ()

It's 100% repeatable, for example by running the first tutorial and clicking the shield to open realm view when instructed to.

Hoping it will be fixed soon, because CK2 seems awesome

Xubuntu 12.10, x86_64, 3.5.0-21-generic. Nvidia 310.14 on a GTX 660 Ti.

Here's a bit more info. The fact that two threads are doing audio stuff concurrently tingles my spidey sense. Also, those registers are pointed nowhere (beyond the heap). It's not clear to me why the add instruction is there. Note that I was opening a different view than the previous backtrace. Hope this helps.

Please try this fix: http://forum.paradoxplaza.com/forum/showthread.php?658767-Temporary-Mac-Fix

Report back if this solves your problems or not

Edit: Conqen, thanks for the code, I will look into adding it to our Linux builds

Legerdemain · Jan 17, 2013

Seems to be working for me

Thank you kindly!

drFlK · Jan 17, 2013

Played for about 4 hours without a problem.

Thanks for the quick fix.

Edit: Didn't test the Tutorial until right now. It fixes the crashes playing a normal game but not during the tutorial. Still crashes clicking on the realm shield.

Hi,

Seems to work for me

. Thanks for the fix!
