This is a bug in the middle-end:
;; if (ABS_EXPR <xi1> != 1) (void) 0; else goto <L3>;
(insn 29 27 30 (set (reg:HI 44)
        (mem/i:HI (symbol_ref:HI ("xi1") [flags 0x40] <var_decl 0x415784a4 
xi1>) [2 xi1+0 S2 A8])) -1 
(nil)
    (nil))

(insn 30 29 31 (set (reg:HI 45)
        (mem/i:HI (symbol_ref:HI ("xi1") [flags 0x40] <var_decl 0x415784a4 
xi1>) [2 xi1+0 S2 A8])) -1 
(nil)
    (nil))
