From Brian Paul:
The glXReleaseBuffersMESA() function in DRI's libGL is just a no-op stub so
I'm not sure where the segfault is coming from.

I think it's clear that SDL should check the GLX extension string for
"GLX_MESA_release_buffers" and only call glXReleaseBuffersMESA() when the
extension is present.

Setting Sam as "QA Contact" on all bugs (even resolved ones) so he'll definitely be in the loop to any further discussion here about SDL.

Comment 3 marchesin 2006-01-31 17:08:10 UTC 
Btw, if you leave this code in, ExtensionSupported("glXReleaseBuffersMESA") is definitely wrong. ExtensionSupported looks at gl extensions (while this is glx) and the extension name is GLX_MESA_release_buffers, not glXReleaseBuffersMESA.
Comment 4 Sam Lantinga 2006-03-19 03:14:32 UTC 
glXReleaseBuffersMESA has been removed.
