Still looking for a review of this small patch to help detect
potentially unsafe calls to __builtin_{frame,return}_address
(with an argument > 2) that tend to either return bogus values
or lead to crashes at runtime.
The problem the function can cause was originally reported in
pr8743 and resolved by adding a note to the documentation. This
patch tweaks the documentation further to make the risks of
using the function that much clearer.

Thanks
Martin
