Mac OSX xcode command line tools v9.0

Hi,

I guess I am having a similar problem:
I have a macbook pro 2016 running macOS Sierra (10.12.6) and I have installed root6 via homebrew and it has been working without any problems.

This morning I updated Command Line Tools to version 9.0, and this happens to crash with root:

francescolosterzo ~$ root -l 
input_line_1:1:10: fatal error: file '/Library/Developer/CommandLineTools/usr/include/c++/v1/new' modified since it was first processed
#include <new>
         ^
input_line_3:36:10: fatal error: file '/Library/Developer/CommandLineTools/usr/include/c++/v1/string' modified since it was first processed
#include <string>
         ^
input_line_7:2:10: fatal error: error opening file '/Library/Developer/CommandLineTools/usr/include/c++/v1/string':
#include <string>

As you can see above I can’t even open root without having this problem.
Do you foresee any permanent fix to this?

What shall I do? Is reverting to the previous version of Command Line Tools an option?

I tried to reinstall root from scratch (always via brew) but this didn’t fix the problem.

Thanks!!
Francesco
