Description Piotrek Juzwiak 2011-03-07 21:34:58 UTC

X server requires MPROTECT flag disabled if mesa has been built with gallium & llvm use flags. Using classic mesa backend doesn't trigger it since it doesn't use llvm.

I have temporarily fixed by disabling MPROTECT flag on /usb/bin/X but i guess this is very bad idea especially for X. I believe it is due to LLVM having JIT compiler and X on gallium can't start without it?

Reproducible: Always

Steps to Reproduce:
1.Emerge mesa-9999 with gallium&llvm flags on hardened profile
2.(Re)start X server 
3.
Actual Results:  
X server crashes with LLVM stating it can't map memory as RWX

Expected Results:  
X server starts just fine
