Any known crash causers on SFML2?

[JannoT]

Anything known to cause crashes in SFML2?
Becouse i get a ugly crash after closing my program.

Code: [Select]


Program received signal SIGSEGV, Segmentation fault.
In atioglxx!DrvRealizeLayerPalette () (C:\WINDOWS\system32\atioglxx.dll)

Call stack

Code: [Select]


#0 6903A59D atioglxx!DrvRealizeLayerPalette() (C:\WINDOWS\system32\atioglxx.dll:??)
#1 0319C890 ??() (??:??)
#2 6908BDE0 atioglxx!DrvValidateVersion() (C:\WINDOWS\system32\atioglxx.dll:??)
#3 00000000 ??() (??:??)


For me this looks like sfml 1.5 font bug, but that should be fixed and i havent even used sf::String in my code, yet.

My code: http://pastebin.com/m3ee064d6

I use Mingw and i use the SFML Release DLL's, compiled by myself. REV: 1274, and i am not mixing debug and release lib's.

OS: Win XP SP3
CPU: Intel Celeron 2.5GHz  :oops:
Graphics card: ATI Radeon HD2400

And also: SFML 1.5, rev 1274 doesnt crash with the same code.

Out of topic, just I'm curious. You are on Windows. Why mingw and not VC Express? Many of troubles would fade away. :wink:

I have no idea, sorry. Can you use the debug versions to get more informations about the crash with your debugger?

I have the same problem with the current version, and a little more information:

The segfault described above is thrown for me in WglContext.cpp:93: wglMakeCurrent(NULL, NULL);

I don't know if that is of any help: Since I really have no idea about OpenGL, I tried removing said line and compile SFML2 again. The error just wanders to the next line: wglDeleteContext(myContext);

Removing the

Code: [Select]

if (wglGetCurrentContext() == myContext)
     wglMakeCurrent(NULL, NULL);
wglDeleteContext(myContext);
removes the error. (What happens if I don't delete the context? May I work this way till a fix is figured out?)


OS: Win 7 64bit
Graphics Card:    ATI Mobility Radeon HD 5650


Oh, and also no idea if that is of any help, while I googled a little I found this:
https://svn.lcube.de/dev123/projects/cafu/trunk/Libs/OpenGL/OpenGLWindow.cpp
Especially one comment strikes me as interesting:

Code: [Select]

// WARNING: Omitting the following line worked when this library was a static library.
// When it became a shared library, the next call to glXMakeCurrent() caused a segmentation fault without this line.
// That's strange. Probably it's just a driver bug on my machine, but I thought I'd better mention it...
glXDestroyContext(DisplayPtr, RC);


edit:
Curious and curiouser: When I use static linking, everything works fine.

Because some people like MinGW.

I have the same problem ( with SFML2, mingw, dynamic link ). I've got a ATI Radeon 5870, and I also get a lots of users feedback concerning this problem.

But I thought you were aware of this problem Laurent, it has been discussed here for example : http://www.sfml-dev.org/forum-fr/viewtopic.php?t=1535&postdays=0&postorder=asc&start=255
