Yes this is an aliasing violation inside of the sources of vortex
see PR 23449.


Note 127.gcc has similar issues too but I don't know why nobody have
brought this up to SPEC.  I was trying to get Apple to do it a couple
of years ago and then trying to get SUSE to do it but I could never get
anyone with enough courage to propose my fix of using memset instead of
casting.
