How are you compiling Dolphin? Are you using a Debug build and did you disable optimizations?

Any way you could bisect this crash to find the first crashing revision? Can't reproduce that issue here.
Updated by shadowflash over 11 years ago
I was compiling just with cmake . -DCMAKE_BUILD_TYPE=RelWithDebInfo && make but i can make a full debug too.
And yeah i will try to find which revision introduced that crash.

Thanks! We would really appreciate if you could do that quickly - we were planning to release a new version of Dolphin today, and it would be a shame to have a crashing bug like that in a stable release :P

Well 3.0-890 is fine so that leaves about 20 revisions to check and i'll skip anything with changes that can't affect video in any way to make it faster.

After i've found that backtrace is always different i started to think that crash isn't related to OGL backend in any way
It's here, changed unsigned short _mode = 0; to unsigned short _mode; and no crash, everything boots fine. Got latest revision, changed that line - everything is fine.
Still have to find which revision broke Phalanx WiiWare though.

- Status changed from New to Work started
Could you try the latest master version and confirm that this is now fixed?

According to what you said in comment 5, this should be fixed.
