我正在尝试查明我们遇到的错误，这是我所能做到的。
我们正在创建一个内存指针，然后将其由C库填充：
hash_result_pointer = FFI::MemoryPointer.new(:uint8, 144)
CLibrary(hash_result_pointer)
我们正在通过Docker在macOS High Sierra和Ubuntu Xenial上对此进行测试。这是两者的结果：
macOS High Sierra
p hash_result_pointer.read_string
# "\x0F\xE1\x11%\v\xC2)a@"
p hash_result_pointer.read_array_of_uint8(144)
# [15, 225, 17, 37, 11, 194, 41, 97, 64, 0, 32, 156, 191, 7, 38, 254, 119, 123, 104, 145, 2, 160, 137, 112, 10, 193, 71, 15, 3, 134, 245, 5, 6, 24, 234, 1, 100, 4, 188, 45, 158, 28, 120, 130, 42, 62, 152, 15, 1, 97, 48, 16, 0, 41, 125, 5, 4, 20, 142, 3, 10, 3, 156, 1, 65, 10, 122, 15, 52, 67, 52, 109, 38, 13, 18, 128, 47, 44, 53, 90, 23, 72, 32, 82, 56, 17, 42, 126, 57, 71, 71, 80, 9, 180, **65**, 80, 18, 9, 5, 56, 26, 17, 2, 121, 21, 52, 21, 92, 74, 19, 92, 83, 84, 45, 89, 123, 34, 117, 75, 89, 8, 7, 19, 12, 8, 5, 8, 8, 25, 1, 20, 14, 48, 3, 24, 57, 12, 32, 18, 90, 3, 35, 15, 34]
Ubuntu Xenial通过Docker
p hash_result_pointer.read_string
# "\x0F\xE1\x11%\v\xC2)a@"
p hash_result_pointer.read_array_of_uint8(144)

如您所见，在两个环境之间有一个数组元素相差1（65对66）。我不知道为什么会这样，而且我也不知道是什么原因造成的，我应该在哪里进一步观察。不胜感激！
