Question

我有一个问题，我正在处理WORD（2字节无符号整数）。以下是我经常运行的命令

import mySimLib
mySimLib.init()
strPtr = mySimLib.strInit( 200 )    #where 200 is the number of characters I want in the
                           #string. strInit returns a malloc'd pointer
wPtr = mySimLib.wordInit ()         # where wordInit returns a malloc'd pointer to a WORD.
mySimLib.Write ("Title", "Data", 4) # 4 is the number of bytes required to store data
mySimLib.Search ("Title", strPtr, 200, wPtr) #Search finds the record with same title,
      #copies the data into strPtr up to the number of bytes in the record - as long as
      #the number of bytes in the strPtr is greater. 

mySimLib.printWord (wPtr) #Since I cannot use python to dereference word pointers, I call a C function to print it out.

此时，我的程序崩溃了。它抛出异常（读取违规）或某些GC Object Already跟踪错误。问题是 - 我有一个字符串打印功能，当我打印它时永远不会失败。当我试图打印这个词时，我确实遇到了错误。

这是我的wordptr启动功能：

unsigned int * wordInit () {
    unsigned int * d = malloc ( sizeof ( unsigned int ) );
    *d = 0;
    return d;
}

这是我的打印功能：

void wordPrint (unsigned int * d){
    printf ("\nWptr: %d",*d);
}

我不知道我在这里做错了什么，但是这些崩溃非常不稳定和烦人。

Python / SWIG：GC对象在尝试使用C函数从SWIG取消引用指针时已经被跟踪
