Segmentation fault after running for 10 seconds

[Joseph S]

this only seems to be affecting the 64 bit version, its fine on my 32-bit netbook, whenever you try to play a game it either instantly crashes or it plays then 10-15 seconds later the app crashes, running it in the terminal reveals its a segmentation fault.
it looks like its crashing at "Loading SDL sound with pulse driver..."

What You Expected to Happen: The emulator to run the game with sound.
What happened instead: The emulator crashes with a Segmentation Fault.

No one else has this problem?

This is still affecting me and is a real problem, will try reinstalling to see if it occurs again.

Again this is happening on x86_64(64-Bit) not the normal x86(32-Bit) version.

Today I ran the program with strace and it didn't crash, but without strace i still have the same issue,
interestingly i also got this to appear one time, when fceux crashed from the command line

*** glibc detected *** fceux: double free or corruption (!prev): 0x0000000001bbf250 ***
Segmentation fault

why would the program not crash when running with strace?
I thought strace records system calls and signals of a program, why would it work with it, and
not by itself?

why does this only affect me? i even have a different motherboard, ram, and CPU now then when i first reported this. and i
still have the same exact problem.

please help.

Hi,

It's working fine here en amd64. Could please try moving $HOME/.fceux to somewhere else and restart the game? If it's not working, could you try purging fceux (with sudo apt-get purge fceux), deleting $HOME/.fceux and reinstall it?

thanks,
Fabrice

[Joseph S (supermariolinux)]

ok, just tried all of that and it still segfaults. :(

Hi,

Could you please follow the instructions at https://wiki.ubuntu.com/Backtrace#Generation and attach the generated files?

Thanks,

GRR, the program wont crash when its running through gdb,

but it crashes without it?

I have the same issue with kubuntu 11.10 I386 version running on a 64bit capable CPU.

I can also get it to works by running with strace or if I specify the rom file via command line when starting fceux.

Furthermore it works fine if I run the program as root using sudo. Since sudo works could this be a problem with access rights between sdl and the pulse sound driver? And since it works if I don't use the GUI maybe its a bug with the sound config dialog in the GUI?

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

This is likely related to the binary-only nvidia driver, and may be caused by it. See: http://sourceforge.net/mailarchive/message.php?msg_id=29448314

[Lukas Sabota (punkrockguy318)]

The latest upstream version of fceux (2.2) resolves a variety of issues with the closed-source nvidia blob drivers -- perhaps the latest fceux could get backported in an attempt to resolve this issue?

Same problem for me. I'm running version 2.1.5 . I played ninja gaiden a long time, without any problem, (with a logitech precison).
Then I started double dragon 2 and here problems started.

Oops forgot this: linux mint 13 64 bits .

Version 2.2.1.1, apprently solved the problem.
