hello world and its .gc* files which make gcov segfault

If I compile a hello world program with clang --coverage (manually specifying
libclang_rt.profile-x86_64.a; see bug 15953) and then run the program, .gcno
and .gcda files are produced as expected. However, when I run "gcov hello.c",
it fails to read the files (and even segfaults - issue reported as GCC bug
57234). I'm attaching a .tar.gz with hello.c and the .gcno and .gcda files
produced by clang r181582.
