--- Comment #1 from Schimpe, Christina <christina.schimpe at intel dot com> ---
Thank you for reporting this.

I looked at the logs and saw that GCC 7 is being used, which doesn't support
shadow stacks (-fcf-protection). 
It seems the test runs on a system with a recent kernel (which supports CET
shadow stack) but an older version of GCC. Due to that CET shadow stack is not
enabled for the program and the register appears as "unavailable".

Would you mind sharing the kernel version as well?
