--- Comment #9 from Thomas Preud'homme <thomas.preudhomme at arm dot com> --- Sorry, I didn't realize it was preventing bootstrap. I have a small patch that disable the optimization for STRICT_ALIGNMENT target but was reluctant to use it as is because this effectively disable this optimization for ARM. But given the situation the patch could be applied temporarily to avoid the bootstrap failure and a better solution be commited later.
