Roger, this appears to be caused by your patch:
* reg-stack.c (struct block_info_def): Correct grammar typo.
(compensate_edge): Clean-up. Perform as little work as possible
when src and dest stacks match. Avoid modifying block_info.
Reorder and simplify assertion checks. Avoid unnecessary copying
of regstack structure.
(convert_regs_1): Set the done flag here...
(convert_regs_2): ... instead of here.
