Looks like graphics driver binary compatibility has been broken again. :-(
When trying to load the nvidia driver I get:
Program received signal SIGSEGV, Segmentation fault.

I'm assuming Composite caused this to happen, by the driver stomping on some
memory somewhere due to structure changes. Could you check to be sure that if
#define BuildComposite NO
to your host.def, it goes away?
Thanks for the hint. I'll give it a try and let you know.
Yes, disabling build of Composite fixes the problem. nvidia driver now works
again. Hmm ...
Someone needs to track this one down as maintaining ABI compatibility is one of
the goals for this release.
My only thought currently is the two extra fields in the VisualRec structure for
alphaMask and offsetAlpha might be causing the problem, but I haven't looked
very far into this yet.
Adding Keith Packard and Eric Anholt on the CC list for their comments.
I removed the new fields in the Visual structure related to making core color
allocation automatically set alpha bits in returned pixel values.
Aside from the new screen_x/screen_y fields in pixmaps (which we hope aren't an
ABI issue), there shouldn't be any other ABI changes controlled by building with
Thanks, Keith! I'll give it a try ASAP (this weekend for sure) and let you
know about the results.
Just verified. The nvidia driver works fine again. :-)
