Yes, this is a known limitation. The documentation talks about the
problem with tail-call optimization:
http://docs.sun.com/app/docs/doc/817-6223/6mlkidln8?a=view
This isn't a tail call issue. The leaf function has the true caller's
return address (in O7), but never creates a stack frame. The lack of a
stack frame is what confuses dtrace, I think.
