This looks like reordering is proper. When schedule-insn2 is run for

Maybe bb reorder got the basic block structure wrong, and the barrier is
not supposed to be part of the basic block. In fact, looking at
bb-reorder.c, I see this
/* Make BB_END for cur_bb be the jump instruction (NOT
the
barrier instruction at the end of the sequence...). */
BB_END (cur_bb) = jump_insn;
Maybe it is getting this wrong someplace else in the file. This might
already be fixed in current sources, so you could try looking for an
existing patch to fix it.
