Hmm, I think this is a reload or a recognizing problem.
inside reload (when adding the LABEL_REG), we have the following instruction:
(jump_insn 169 222 170 19 (set (pc)
        (label_ref:DI 172)) 515 {*indirect_jump_rtx64} (nil)
    (expr_list:REG_DEAD (reg/f:DI 66 [ #ref#6#19 ])
        (nil)))

But this is not an indirect_jump_rtx64 at this point but instead just a jump.

I cannot debug it further than this sorry.
