The problematic instruction (insn 1717) is generated from:
;; vect__1095.501_3524 = MEM[base: vectp.499_3571, offset: 0B];
(insn 1717 1716 0 (set (reg:V2DF 1511 [ vect__1095.501 ])
(mem:V2DF (reg/f:DI 638 [ vectp.499 ]) [7 MEM[base: vectp.499_3571,
offset: 0B]+0 S16 A256])) channel.f90:247 -1
(nil))
