I think for errors that can be triggered by data corruption, we ought to
produce resonable error messages in both IN_LIBGCOV or for offline tools.
Just unwound sequence if(...) gcov_error seems fine to me in this case,
but we may also have assert like wrapper.
I see we do not provide gcov_error outside libgcov, we probably ought to map
it to fatal_error in GCC binary.

thanks,
