Sorry more accurately:

Showing frame-relative/non-readonly reference to "abcde" initializing tree/rtl type which is wrong:

(insn 12 11 13 1 (set (reg:HI 44)
        (symbol_ref/f:HI ("*.LC0") [flags 0x2] <string_cst 0x160b840>)) -1 (nil)
    (nil))

(insn 15 35 16 2 (set (reg:QI 0 r0)
        (mem/s:QI (reg:HI 44) [1 S5 A8])) -1 (nil)
    (nil))


Showing readonly reference to {'a','b','c','d','e') initializing data which is correct:

(insn 21 20 22 3 (set (reg:HI 52)
        (symbol_ref:HI ("C.3.1150") [flags 0x2] <var_decl 0x167e438 C.3>)) -1 (nil)
    (nil))

(insn 24 81 25 4 (set (reg:QI 0 r0)
        (mem/s/u:QI (reg:HI 52) [2 C.3+0 S5 A8])) -1 (nil)
    (nil))
