--- Comment #3 from Andev <debiandev at gmail dot com> ---
This seems to be specific to some latest Intel CPUs. I am not sure which other
CPUs are affected. There is no official errata for this behavior AFAIK.
As Alexander suggested, it would be a great idea to have a work around for this
in gcc for these specific CPUs.
