Created attachment 27002 [details] GDB Backtrace of the crash After a recent version bump of Mesa I can no longer start X due to a crash in intel_renderbuffer_set_region. The backtrace shows a crash due to a NULL region being passed to it. -- chipset: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) -- system architecture: x86_64 -- xf86-video-intel: 2.7.1 -- xserver: 1.6.1.901-r3 -- mesa: 7.4.3 -- libdrm: 2.4.11 -- kernel: 2.6.30 (Clean Linus Tree) -- Linux distribution: Gentoo -- Machine or mobo model: Efficient PC ASUS (ICH7) -- Display connector: TMDS-1 KMS is not enabled (see bug 22225)
Can confirm the crash introduced in Mesa 7.4.3, downgrading to 7.4.2 fixes the problem.
OK, fixed in Mesa with commit 1dbbc39f48ce5f9aa63ab42930b14e48938b326f Looks like a Mesa 7.4.4 release will be needed...

If you think it's really a different bug I can raise a new bug for this crash or wait for the 7.4.4 release so I can test properly. Any idea when a 7.4.4 build will be released?
That assertion was also fixed. Commit 4b8cd0b0ad48c3b0129451924f7461ffcbbc8597 I'll try to release 7.4.4 today.
