[Rascarcapat]

I'm sorry but I'm not sure I understand.

Is this how I should post the dump ?
If so how can I read the file ?

Or is this the "result" of my dump ?
If so what does it mean ?

[shuffle2]

Rascarcapat: yes you did it properly. My post just shows what is causing the crash, so that developers can work on fixing it.

[shuffle2]

Rascarcapat: btw, did this happen on older versions of dolphin?

[Rascarcapat]

I only discovered Dolphin about a month ago (and oh yes, it is wonderful).

And it's been happening since then, with all versions I tried.

[shuffle2]

Did some further looking...(this is the second dump, but it's the same problem):

Code:

00000000`0134f200  00000000`1d2a0000

So it's just a problem of reading off the end of s_video_buffer because of this "+ three" adjustment or whatever.

[Rascarcapat]

Well thanks for the help.

Is there anything I can do to prevent these crashes ?
Or should I just wait for a fix ?

[shuffle2]

Just wait for a fix

[shuffle2]

Rascarcapat this version should fix it: http://dl.dolphin-emu.org/prs/pr-1676-dolphin-latest-x64.7z
it should be in master soon, so then regular builds will include the fix.
