Subject: zsnes is randomly frozen

Date: Wed, 05 Mar 2014 17:32:25 +0100

Package: zsnes
Version: 1.510+bz2-6
Severity: important

Dear Maintainer,

        Playing "Chrono Trigger" (the only one game i have...) the image
freezes, and a part of about 200 miliseconds of the sound is played in a
infinite loop. I have to kill the emulator from a terminal, because neither the
emulator nor the window responds to any action.

        I guess that more information could be useful, but I don't know how to
obtain it. If you say me how to do, the next time the error appears I could
give you more information about it.

Hi,

I suspect that this is the same as LP#1269676:

https://bugs.launchpad.net/ubuntu/+source/zsnes/+bug/1269676

I could reproduce this bug (with another game) and managed to get a
core dump, but did not investigate deeper.

The two causes I suspect are either a change in binary compatibility
due to hardening (see #727781), or a multiarch issue with SDL.

Thanks for this bug report!

[Message part 1 (text/plain, inline)]

Hi,

It seems there is a type conversion issue in sem_GetTicks. tv_sec is only
"long", and on i386-linux the long arithmetic makes the function return a
very large value after ~2148 seconds.
After that it appears the frame rate limiting code just keeps calling
SDL_SemPost, until it gets to MAX_INT and hangs.

You can systematically add 2140 to now.tv_sec in sem_GetTicks to reproduce
the bug without waiting 35mn.

I generated a patch using the Ubuntu (14.04) package sources, as that's
what I have, but the issue comes from one of the debian patches, and I
think it should apply cleanly.

Regards,

The patch looks good to me. Without the cast, the computation is done
on long arithmetic and the result is extended to unsigned long long.

I'll test it and release a new package if it's fine.

Thanks a lot for the debugging and the patch!

Indeed, what a good catch!
