I've tested CLANG compilation with 9.0.1 without this patch,
but couldn't hit the above mentioned error.
# clang --version
clang version 9.0.1 (Fedora 9.0.1-2.fc31)
However, after grabbing CLANG 3.4.2, I could see the error.
# clang --version
clang version 3.4.2 (tags/RELEASE_34/dot2-final)
This patch fixes it and the fix is correct too.
Thanks for fixing it.
