This is due to the following invalid mem that ends up in the
"*extend<mode>si2_compact_snd" pattern:
(insn 8 5 10 2 (set (reg/v:SI 171 [ __fill ])
(sign_extend:SI (mem/c:QI (plus:SI (plus:SI (reg/f:SI 145 ap)
(const_int 12 [0xc]))
(const_int 4 [0x4])) [0 __fill+0 S1 A32])))
locale_facets_nonio.h:1562 241 {*extendqisi2_compact_snd}
(expr_list:REG_EQUIV (mem:SI (plus:SI (reg/f:SI 15 r15)
(const_int 4 [0x4])) [0 S4 A32])
(nil)))
in function "decompose_address":
inner = (plus:SI (plus:SI (reg/f:SI 145 ap)
(const_int 12 [0xc]))
(const_int 4 [0x4]))
