Note that this is important for other tools as well e.g. Asan. I've
posted patch a while ago to add fail-safe backtracking APIs to libgcc
in https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01869.html (the
latest ping is https://gcc.gnu.org/ml/gcc-patches/2017-07/msg00447.html)
but it didn't get too much attention to date. Would be great if
someone could take a look.
