Inside the loop, the\ncondition to skip processing extra bytes is:\n\n if (i > mxt_obj_size(object))\n continue;\n\nSince i is a 0-based index, the valid indices for the object are 0 through\nmxt_obj_size(object) - 1.\n\nWhen i == mxt_obj_size(object), the condition evaluates to false, and the\ncode processes the byte instead of discarding it.\n\nThis causes the code to calculate byte_offset = reg + i - cfg->start_ofs\nand writes the byte there, overwriting exactly one byte of the adjacent\ninstance or object.\n\nUpdate the boundary check to skip extra bytes correctly by using
