This tends to happen if for some reason duplicate tapsets are found by
systemtap (as might happen if two different versions get installed on
top of each other), or if something is wrong with the x86-64 tapset
code, or if one tries to run a tapset script directly (which would
duplicate the copy later found during tapset search).

My guess is that the latter is the case.  One should not in general
run a file under tapset/.
