Preprocessed test case (compressed with tar and bzip2)
This is very recent that it now hangs while compiling the attached file on
x86_64 using these cmdline arguments
/mnt/oe/openembedded-core/build/tmp-glibc/sysroots/x86_64-linux/usr/bin/clang-4.0
-cc1 -triple x86_64-oe-linux -S -o a.s -x c ~/a.c -vectorize-slp -O2
-target-cpu corei7

it works.
