Thanks for the fixup, the problem didn't happen on my system.  This usage 
of sse3 intrinsics inside installed STL headers seems a bit unfortunate 
(not to mention the dubiousness of placing a 180 line function containing 
11 loops nested to level 4 for arcane functionality into a header; but I 
guess this battle is lost with STL).


Ciao,
Michael.
