Is this also true for 4.17?
Compiling 4.17 on Ubuntu 17.04 x64 with clang 4.0 does not work for me:
clang: error: unable to execute command: Segmentation fault (core dumped)
clang: error: clang frontend command failed due to signal (use -v to see invocation)
clang version 4.0.0-1ubuntu1 (tags/RELEASE_400/rc1)
