compiz crashed with SIGABRT in assert() from intel_resolve_map_set() from intel_miptree_slice_set_needs_depth_resolve() from intel_renderbuffer_set_needs_depth_resolve() from brw_postdraw_set_buffers_need_resolve()

Compiz crashed, and X went down with it so I had to log back in. This dump was in /var/crash afterwards.

I just filed bug 1042092, for gnome-control-center crashing, with a similar trace. I think that might be a dupe of this, but I'd love to get a more experienced opinion. Thanks!

[Edward Donovan (edward.donovan)]

Well, the retracer duped my bug 1042092 to private bug 1041891. So, for now, instead of learning more, I know less. :(

Thanks anyway.

[Edward Donovan (edward.donovan)]

Ok! Now bug 1041891 is public, and the stacktrace is much the same. In part:

  intel_resolve_map_set at intel_resolve_map.c:46
  intel_miptree_slice_set_needs_depth_resolve at intel_mipmap_tree.c:890
  intel_renderbuffer_set_needs_depth_resolve at intel_fbo.c:908

I'm still not 100% sure, but confident enough to mark this a dupe, I guess. Thanks.
