I've added gcc_assert (last_basic_block >= NUM_FIXED_BLOCKS) line
to init_resource_info and confirmed that trunk and all released branches
fail with the testcase given in #1 for sh4-unknown-linux-gnu.
Perhaps

  if (optimize > 0 && flag_delayed_branch)
    dbr_schedule (insns);

in sh.c:sh_output_mi_thunk might not be a big deal.  I'm testing
a patch which simply removes these lines.
