as discussed in
[PATCH] stack: Add new '-n MAXFRAMES' option. Resolve addresses after unwind.
I have found I forgot to implement what GDB has as
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
I find it easier in the case of elfutils as all supported unwinding archs have
grows-down kind of stack.
It breaks support for -fsplit-stack (GDB gdb.base/morestack.exp) but that is
IMO an add-on extension which just coincidentally worked with current
checked-in elfutils unwinder (I did not test it).
