That's what I wanted to try too, and will do soon. As to why we never
heard of this before - the only affirmative answer would be from someone
better able to undertand the docs than me.  But here's a wild guess: the
fact that GDB stopped one instruction too late is invisible to the user
99% of the time. What triggered me seeing it was a change in code
generation which caused the update to be at the penultimate instruction
of a function. I wouldn't have seen it if the update was anywhere before
that.
