Updatet to mesa-8.0.2 rebased the needed patches on top of 8.0.2 maybe you want to pull my package "llvm-stable" for now, or revert llvm to 3.0, because llvm 3.0.99 breaks mesa right now OBS-URL: https://build.opensuse.org/request/show/114850 OBS-URL: https://build.opensuse.org/package/show/X11:XOrg/Mesa?expand=0&rev=208

Subject: [PATCH] When glXBindTexImageEXT is called and SWrast is used there
|
|
will be a crash when sPriv->swrast_loader->getImage() is
|
|
called from swrastSetTexBuffer2(). Reason: no memory has
|
|
been allocated for the destination thus texImage->Data is
|
|
NULL. Call ctx->Driver.TexImage2D() to initialize this. If
|
|
memory has been allocated in a previous call free it first.
|

for 8.0.1
|
|
|
|
Ported to 8.0.2
