Summary: DIG: overlapping memory in memcpy() call

Initial Comment:
eriktorbjorn mentioned on irc the following valgrind
warning that occurs with the dig just after the intro
has been escaped, I subsequently confirmed it and here
it is...

==20575== Source and destination overlap in

(timer.cpp:99)


If these sections of memory are indeed supposed to be
overlapping memmove() should be used, otherwise this
needs to be fixed.  Either way it needs attention.

Latest CVS, Linux et cetera
