I'd say that this is a "bug" in GCC, that doesn't call mpfr_free_cache()
before exiting. Now, this isn't really necessary in practice since the
memory will be freed anyway.
Jerry - does this fix it?

Hi Kaveh,
Yes this fixes the mpfr related memory leak. The cgraph related leaks are still
in trunk.
