--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r0-58166-g6de9cd9a886ea695aa892c3c7c07818a7b7e9e6f.
The problem is in the
/* If a const aggregate variable is being initialized, then it
should never be a lose to promote the variable to be static. */
optimization. Either we shouldn't do that optimization if DECL_REGISTER is
set, or we should clear DECL_REGISTER. If the latter, we should still punt on
DECL_HARD_REGISTER.
