Emulator Issues #3262
closed
Segmentation fault on Fedora
0%
Description
What steps will reproduce the problem?
- co latest version
- scons flavor=debug
- Launch dolphin-emu
- Attempt to start any game (several iso backups locally)
What is the expected output? What do you see instead?
I believe the expected output is a separate game window. Such a window appears. Then disappears shortly after. Resulting in the initial terminal used to launch dolphin reporting the Segmentation Fault (core dumped)
Dolphin version with the problem? Other Dolphin version without the
problem?
Revision 6226. I have thus far been unable to get any version to progress beyond this.
32-bit or 64-bit and any other build parameters?
64 bit. Scons flavor=debug / flavor=release (have tried both. debug is what i'm on now)
OS version and versions of tools/libraries used?
Os Fedora 13 64.

I saw in issue 2790 skidau asked a question about NX/DEP. In /proc/cpuinfo NX is listed as one of the CPU flags.
Also I really understand how to use gdb but here is the backtrace since I saw that this is requested often.
(gdb) backtrace
#0 0x0000000040a00693 in ?? ()
#1 0x0000000041a0004e in ?? ()

Im not sure why I get less than everyone else :-s.
Thanks in advance for any help.

- Category set to jit
- Operating system N/A added
This looks like Jit problem to me, maybe caused by NX.
skid, any ideas?

Hi
I thought that might be the case. So i tried to disable NX.
First I used "sysctl -w kernel.exec-shield=0". This did not affect the outcome.
Next I tried appending "exec-shield=0" to the kernel line of grub.conf. Still no change.
Thanks for looking into it so quickly.

What are your hardware specs (cpu, video, mobo chipset, audio)?
Updated by yogacypher over 13 years ago
From what I can gather;
CPU: core i7-820QM processor (1.73GHz)
Video: GeForce GT 330M GPU (1GB VRAM)
Audio: not sure how to find this
Mobo chipset: not sure about this either but "sudo dmidecode | more" gives lots of info so I attached it.

If the problem is not caused by NX, it is probably something to do with alignment or ABI on Fedora. I do not have a Fedora machine handy.

Do you happen to have any pointers on how to investigate this myself? I am unfamiliar with either of those terms.
Thanks again.

- Status changed from New to Accepted
This is a problem caused by LoadStorePaired, the same problem that affects OS X. Disabling LoadStorePaired will let dolphin run just fine.
