gcc_assert (!delete_unreachable_blocks ());

but that didn't work.  I guess somebody creates unreachable blocks
sometime between the tree optimizers and rest_of_handle_jump....

That may well be caused by the builtin optimizers or by some tricky cases in the expander. Also note that rest_of_handle_jump is also run at -O0; it may be well expected that there are some unreachable blocks despite the small cfgcleanup pass executed at -O0.
