The original interpreter the "autovectorized" one was compared against was also compiled with -O3 as one can see in the updated node.

All runs stable - at least on the P4 - don't know about other architectures, but sse2 is not of much interest there - I guess. Probably Mac/PPC users could experience similar results if GCC supports the altivec engine.
