it is so strange that we can pass the go test smoothly.
what's more, C.memcpy copy four times longer buffer than the real length, it never core dump(system call libc's memcpy in low level), and set all the data to 0 as normal.

Oh, no, we malloc four times memory.......
cbuffer = C.malloc(C.size_t(len(p.Content))), it absolutly will run smoothly because I waste the rest buffer.
weird, by the way. : )
