Though I don't know any details about the error dtrace is emitting,
I would suspect it's not that the frames are paged out but that the
addresses are actually invalid - such as you'd see if you have
certain kinds of aggressive optimisations turned on
I all have optimizations disabled (-O0) and ufunc(arg0), i.e. top of
the stack does work, e.g. @[ufunc(arg0)] = count().
Thanks, Joel
