Your bug report is about slowdown in *compilation* time. I 
wondered if the longer compilation time is due to the better 
(faster) generated code. But this is not the case either:

$ ./dotbench
initialized arrays of type double
dot_fast: 279 ms
value = 0
dot_slow: 5413 ms
value = 0
dotProduct: 217 ms
value = 0
