Actually it is a bug in Clang, I guess but I cannot register at https://bugs.llvm.org/enter_bug.cgi anymore and maybe this helps you anyway.

I've tried it without the GIT_TAG specification as well. Even if it is a Clang bug maybe something could be done about it. I am using Fedora and the installed Clang package. If there would be an official folly-dev package, I would use it instead.

Would you try revering locally the following change and see if it helps?

Hasn't this commit been done after v2016.12.19.00?

edit:
I am trying an older version now: v2016.10.24.00

Apparently g++ is still used:
libtool: compile: g++ -DHAVE_CONFIG_H -I./.. -pthread -I/usr/include -std=gnu++1y -g -O2 -MT io/async/Request.lo -MD -MP -MF io/async/.deps/Request.Tpo -c io/async/Request.cpp -fPIC -DPIC -o io/async/.libs/Request.o

My calls are:

CONFIGURE_COMMAND CC="/usr/bin/clang" CXX="/usr/bin/clang++" cd "${folly_DIR}" && autoreconf -ivf && ./configure #--prefix="${folly_LIB_DIR}"
BUILD_COMMAND cd "${folly_DIR}" && make -j4

but it seems to use Clang only when CMAKE_CXX_COMPILER and CMAKE_C_COMPILER of my project are set to it. The CC="" and CXX="" calls are ignored? How do I specify clang successfully for autoreconf? Maybe it mixes up two compilers.

edit2:
Found the answer here http://stackoverflow.com/questions/32342886/how-to-configure-autoreconf-to-use-a-different-compiler-than-gcc
Trying it again with only Clang now.

edit3:
My CXXFLAGS seem to be appended only and I had to add -msse4.2 to prevent errors:
libtool: compile: clang++ -DHAVE_CONFIG_H -I./.. -pthread -I/usr/include -std=gnu++1y -std=c++14 -msse4.2 -MT Assume.lo -MD -MP -MF .deps/Assume.Tpo -c Assume.cpp -fPIC -DPIC -o .libs/Assume.o

This is my call now:

autoreconf -ivf
./configure CC=clang CXX=clang++ CFLAGS=-std=c11 CXXFLAGS='-std=c++14 -msse4.2'

I am getting another crash of Clang now which shows the actual clang call:

I believe this has been resolved upstream in Clang, as we've not had more reports of this issue in the last year.
