C17中有如下描述：
7.22.3 Memory management functions
1 The order and contiguity of storage allocated by successive calls to the aligned_alloc, calloc,
malloc, and realloc functions is unspecified. The pointer returned if the allocation succeeds is
suitably aligned so that it may be assigned to a pointer to any type of object with a fundamental
alignment requirement and then used to access such an object or an array of such objects in the space allocated (until the space is explicitly deallocated). The lifetime of an allocated object extends from the allocation until the deallocation. Each such allocation shall yield a pointer to an object disjoint from any other object. The pointer returned points to the start (lowest byte address) of the allocated space. If the space cannot be allocated, a null pointer is returned. If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned to indicate an error, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object.
可见c17中，mallo(0)的行为依赖于各自的实现，可以返回空指针，也可以返回非空指针。
我用gcc 9.3.0验证，malloc(0) 返回的是非空指针。

我的实验是基于PSPNet模型实现二维图像的语义分割，下面的代码直接从得到的h5文件开始往下做。。。 也不知道是自己的检索能力出现了问题还是咋回事，搜遍全网都没有可以直接拿来用的语义分割代码，东拼西凑，算是搞成功了。 实验平台：Windows、VS2015、Tensorflow1.8 api、Python3.6 具体的流程为：...
