swift3 UnsafePointer指针如何销毁

[深海飞鸟]

let str_QueryServerDID1 = @"abcd"
// String转换为CChar
let char_QueryServerDID1:[CHAR] = str_QueryServerDID1.cString(using: String.Encoding.utf8)!
//CChar转换为字符串指针
let UnsafeMPtrDID1 = UnsafeMutablePointer<CHAR>.allocate(capacity: char_QueryServerDID1.count)
UnsafeMPtrDID1.initialize(from: (char_QueryServerDID1), count: char_QueryServerDID1.count)
let UnsafePtrDID1 = UnsafePointer<CHAR>.init(UnsafeMPtrDID1)

因为我需要生成UnsafeMutablePointer<UnsafePointer<CHAR>?>类型的参数已使用C的API，所以制造了UnsafePointer<CHAR>的指针，但是最后发现UnsafePointer<CHAR>不知道如何释放指针！现在因为这个造成内存泄漏App挂了，log如下：
malloc: *** error for object 0x6000002065d0: Invalid pointer dequeued from free list
*** set a breakpoint in malloc_error_break to debug

所以，请教下各位大大有什么办法可以释放UnsafePointer指针吗？

只有手动分配才需要手动销毁
