  "message": "[ArrayOf family] Use memory barrier before accessing array\n\nWithout it, the compiler was reordering and batching the read\nof array length and array[0] if the 0\u0027th member was accessed\nconstantly and function was inlined.  This felt safe to the\ncompiler because HB_VAR_ARRAY is 1, but could be unsafe actually.\nThe memory barrier disallows that.\n\nThis was found by afl/honggfuzz address sanitizers.\nFixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id\u003d49187\n",
