While looking at the DRI overhead, I got curious about x11perf results.
Consequently, I tried a run, just to get a baseline, and segfaulted the
server.
This can be reproduced with:
x11perf -seg100c2
when the DRI is enabled.
Here is a stack trace from a static server built from the TCL branch.
Program received signal SIGSEGV, Segmentation fault.

I'm building the development branch from the XFree86 repository right
now to see if that yields any different results.
