 I see a very similar backtrace here, but this is not the first issue.
 
 When you run X in a debugger, or when you disable its SIGSEGV handler
 with Option "NoTrapSignals" "true", then you see that the first thing
 is a segfault in atexit() where it tries to call a registered handler
 at an unmapped address.
 
 But while X is running, the address is mapped to the shared object
 gallium_dri.so.0.
 
 Looks like the gallium driver is unloaded without unregistering
 (or calling ?) the atexit handler.
