 I suppose we could go with 5 instead of 4, and have dump_trace()
 skip the first one, presuming that this anomoly is not architecture-
 or compiler-dependent.  Or maybe make it macro? 
Did you compile with some optimisation? I think I remember that gcc
only inlines code with optimisation turned on.
I think it makes sense to use
`always_inline'
     Generally, functions are not inlined unless optimization is
     specified.  For functions declared inline, this attribute inlines
     the function even if no optimization level was specified.
here, i.e. __attribute__((always_inline)). I personally prefer inline
functions over macros.
