Hi,
i too hit the X crashing issue. But i am unable to compile the latest
git (10.2-branchpoint-318-g4c7bf8a according to 'git describe')
Here is the errors i get:

Build script (i use it since forever, it is working with enabled llvm
shared libs, but as soon as i touch anything OpenGL related, X crashes.)
