Confirmed, the vectorizer is asking scalar evolution code about a floating point variable, I don't know 
where the bug should be fixed.  I want to say in scalar evolution but I don't know for sure.

Note to reproduce this now on the mainline, you have to remove the static as unit-at-a-time is now 
default at -O1 and above.
