This machine is a Ivy Bridge so has Coreavx ( AVX1) enabled, so some VEX 
usage is allowed.

I removed some avx1 (-Cpcoreavx -Opcoreavx -Cfcoreavx) from fpc.cfg and 
the problem went away for more.

I asked on (FPC) core for a quick comment, and will file it as a bug if 
nobody has a direct hunch. (which would be understandable since I can't 
pinpoint the exact date when this was introduced)
