Which DRI driver are you using?
It looks like two different areas were changed on the 22nd/23rd on the
6.4 branch:
1. main/mm.c - doubly-linked list change
2. main/texenvprogram.c - texture env program cache changes
The thing is, I have doubts that either one would account for a total
failure like you're seeing.
If you haven't done so, you might do a 'make clean' and recompile,
just in case a dependency was missed or something.
