With debugging of this problem, I find that reload_combine_note_store
trips when the rtx dst has the mode BLKmode. This is the rtl that causes
the segmentation fault in the combine phase:
;; Start of basic block 2, registers live: 3 [%r3] 30 [%r30]
(note 95 80 83 [bb 2] NOTE_INSN_BASIC_BLOCK)
(insn 83 95 0 (clobber (reg/i:BLK 28 %r28)) -1 (nil)
(expr_list:REG_UNUSED (reg/i:BLK 28 %r28)
(nil)))
;; End of basic block 2
