reduced parse.tab.c
When compiling GNU Units 2.02 (http://www.gnu.org/software/units/) with clang
3.4 or 3.5, it hangs at parse.tab.c.
It was configured with CC=clang ./configure
It compiles and runs with clang 3.3.
I waited 15 minutes with 3.4 before giving up.
I am using clang 3.3, 3,4 and 3.5 from Ubuntu Trusty.
I also tried the Saucy packages from llvm.org/apt.
Turning off -O2 makes the compile succeeded.
I have tried to reduce a test-case.
clang -O -c units-clang-hang.c
