It's probably PR12517. Looking at the clang binary, it's got a /home/ dir in RPATH: $ objdump -p clang+llvm-3.3rc3-Ubuntu-12.04.2-x86_64/bin/clang | grep RPATH RPATH $ORIGIN/../lib:/home/aadgrand/tmp/LLVM-3.3rc3/rc3/Phase3/Release+Asserts/llvmCore-3.3-rc3.obj/Release+Asserts/bin This will slow things down if the system tries to automount /home/aadgrand. Maybe we should merge r182559
