在Loadrunner 8.0 VU脚本编写时如脚本中包含了二维指针，则报如下错误：
Error: An exception was raised while calling invocation function in interpreter extension cciext.dll: System Exceptions: EXCEPTION_ACCESS_VIOLATION.
如下代码：

#include "web_api.h"

int escape_url_character(char *data, int data_len)
{

    char * transfer_table[][2] = {
        {"+", "2B"}, {"[","5B"},{"]","5D"},{"`","60"},
        {";","3B"},{"/","2F"},{"?","3F"},{":","3A"},
        {"@","40"},{"=","3D"},{"&","26"},{"$","24"},
        {" ","20"},{"<","3C"},{">","3E"},{"#","23"},
        {"%","25"},{"{","7B"},{"}","7D"},{"|","7C"},
        {"\\","5C"},{"^","5E"},{"~","7E"}, {NULL, NULL} };

    int i = 0, j;
    char *buf = (char*) calloc(data_len + 1, sizeof(char));

    while( i < data_len ){
        if( '%' != data[i]){
            strncat(buf, data+i, 1);
            i++;
            continue;
        }

        j = 0;
        while( NULL != transfer_table[j][1] ){
            if( 0 == strncmp(data+i+1, transfer_table[j][1], 2 )){
                strncat(buf, transfer_table[j][0], 1);
                i += 3;
                break;
            }
            j++;
        }

        if( NULL == transfer_table[j][1] ){
            strncat(buf, data+i, 1);
           /* printf("escape_url_character: unhandled sequence: %s\n", data+i);*/
            i++;
        }
    }

    memset(data, 0, data_len);
    strcpy(data, buf);

    free(buf);
    return 0;
}
Action()
{

    return 0;
}

此种情况下将二维指针改为三维数组就能运行通过，即上面代码char * transfer_table[][2] 改为char transfer_table[24][2][3]就能运行通过了。
这也许是LoadRunner的一个bug
