SFML2 Error / Crash message on Vista with ATI drivers
« on: November 13, 2010, 06:28:32 am »
Hello. I am running Windows Vista and built SFML2 using MSYS/MinGW. The examples run but display a "[name of program] has stopped working." error message every time I quit. The problem appears to be the result of a segfault in an ATI graphics driver (atioglxx.dll), in particular, gdb indicates that the segfault occurs at 0x693839fa in atioglxx!DrvGetProcAddress (). To the best of my knowledge, I am using the most up to date drivers. My naive guess is that this may be a result of some sort of multithreading/concurrency problem in the interaction between window cleanup and OpenGL, although I'm not familiar enough with OpenGL or the SFML2 codebase to know where to look next. Any ideas?

It's a known bug, don't worry.

This is a rather significant bug for my purposes. Is there a plan to fix it soon? If not, can you point me in the correct direction towards working on a fix myself?

To fix it yes, definitely, but I don't know if it's going to happen soon. It's very hard to fix.

Use static link to avoid the crash. As for fixing the crash itself, don't even try to do that, it's a pure nightmare ;)
And there's probably no clean solution anyway, so...

Has this bug been reported to AMD (As far as I know, its a bug in the driver and not in SFML, right?)? If they do not know of it, it will never be fixed.

Well, I don't know if it's a bug. It happens at global exit of a DLL, so I don't know if the expected behaviour is well defined.

But I can report it and see what they say.

Any updates on this? (Have you informed AMD about it? Whats their response (if you already have one)?)

This isn't a vista Specific bug. I had it on xp to.
But I expect Laurent will get it fixed.. somehow... lol Maybe ATI will fix it.. who knows.
