Emulator

I noticed just now that if the "Video Backend" is set to "Software Renderer" (through "Config">>"Video Backend") the crash is no longer happening.

After going back to "OpenGL" the issue is back.

Going to commit some VideoConfig cleanups soon. As I'm developing on both Linux and Windows, it should be fixed after that...
Can't give any ETA though.

Thanks, there is no hurry, I can still modify the options by editing gfx_opengl.ini.

@dubigr

and log from r7439 ???
duplicate case issue was closed since r7439 O.o

OK, here is the log:

@dubigr

this log now is a bit strange.

That log is useless in 99% percent of all cases anyway.
Nothing strange about it, apart from the fact that you shouldn't need to run Dolphin as root.

@NeoBrainX

<That log is useless in 99% percent of all cases anyway.>

percentage absolutely excessive.
Log from r7438 is a good example :°D

Anyway log indicates and mark this issue "as invalid" for me.

That log from r7438 was a build log and not a Dolphin console log...

The log doesn't indicate anything.

I think it is my fault by attaching those build logs (7437 and 7438), those are NOT the issue I'm reporting and I only confused things.

I attached them only in case someone was curious, besides, whatever was causing those errors is already fixed in r7439.

As for Dolphin console log (r7439) is posted at comment nr 5.
There isn't much there (other than NeoBra catching me running as root :) )
I changed the verbosity level but this is all I'm getting there.
All I did was start Dolphin and click on "Graphics option" >>> instant crash.

@dubigr

It happens something strange... instant crash is very bad.
I don't know what is the problem, maybe something related to gcc compiler.
You don't have neither warning mex while compiling....
Changes, since last revision worked for you, were "classes template". This can be the cause.
Other linux users after r7438 it seems they don't have crash experiences. :/

I've got something of interesting inside the sourcecode (completely I forgot before). :)

Like I said, I'm rewriting the dialog code anyway... so please don't spam the svn logs :P
You're free to share you findings though, of course ;)

@NeoBrainX
Your attitude is unacceptable.
If you call my waste of time spam, someone is idiot. ;)

W00t ? I'm using Ubuntu 10.10 and it works perfectly...

Not for me, on ubuntu too...

An attempt to run it via gdb and clicking on the video config button produces this:

@florian: what are your gcc optimizations flags? Using -O3 here, trying to lower it to -O2 and see if it's an issue with gcc.

Gcc is the same (4.4.3) and gave no warnings for every revision I tried (working or not).

Anyway, I compiled again the r7439 (the first one that had the crash) and one of the latest one (r7465) on a different system.
This one is MandrivaLinux Cooker (the development and unstable version) on 64-bit.

The GCC version is 4.6.0 and gave a LOT of warnings at build time, but all Dolphin versions compiled successfully and they no longer crash.

The original issue still remains though for the 32-bit installation.

@dubigr

The problem, I think, is a my fault when I fogot to remove even some lines;
Remove these rows and all should work right without problems anymore:
121, 122, 123 (you can see the first line is "void *p = &m_setting;")
137, 138, 139 (here first line is still "void *p = &m_setting;")
Remove these six lines and rebuild.

file is VideoConfigDiag.cpp

Working!

I compiled two revisions (7438 and 7468) using the modified "VideoConfigDiag.cpp" file and Dolphin is no longer crashing when accessing "Graphics options".
The issue is gone now.
Thank you!

working on my system as well!

Closing... try r7472/3
