损坏的双链表：0x0000000003608dc0

Question

我正在调试一个实际上是文件阅读器的代码。代码运行，但在某些行之后我收到错误：

*** glibc detected *** /bin/OPENSUSE_12.2_X86_64/filereader: corrupted double-linked list: 0x0000000003608dc0 ***

调试后我理解问题来自一个名为ReadLongVector的函数，函数初始化和定义如下。问题出在else循环中：

bool floatDS, retVal
if ( floatDS ) {

          retVal = ReadLongVector( floatvec_, 3*numZoneNodes,
                                   velPath, zonePath.str(),
                                   timeStepNumbers_[timeStepIdx], false );

        } else {

          retVal = ReadLongVector( doublevec_, 3*numZoneNodes,
                                   velPath, zonePath.str(),
                                   timeStepNumbers_[timeStepIdx], false );

        }

ReadLongVector功能如下：

template<typename T>
  bool ReadLongVector(std::vector<T> &out,
                                      Integer size,
                                      std::string what,
                                      std::string where,
                                      Integer when,
                                      bool throwEx)
  {
    int dattyp;
    int length = 1;
    int iopt   = __not_stop_if_failed__;
    int nerr   = 0;
    T *datarray;

    if (size < 1) size = 1;
    out.resize(size*length);
    datarray = out.data();

    const std::type_info &tiOut = typeid(T);
    if ( tiOut == typeid(float) ) {
      dattyp = __real_data_type__;
    } else if ( tiOut == typeid(int) || tiOut == typeid(unsigned int) ) {
      dattyp = __int_data_type__;
    } else if ( tiOut == typeid(double) ) {
      dattyp = __double_data_type__;
    } else {
      if (throwEx) EXCEPTION("Data type not supported: " << tiOut.name());
      return false;
    }

    snprintf(what_, sizeof(what_), "%s", what.c_str());
    snprintf(where_, sizeof(where_), "%s", where.c_str());

    readlong_(&dattyp, &nerr,
        what_, where_, &when,
        &size, &iopt,
        (float*)datarray, (int*)datarray, NULL, NULL, (double*)datarray, NULL,
        strlen(what_), strlen(where_), 0);

    if ( nerr == __io_ok__ ) {
      return true;
    } else { 
      if ( throwEx ) CHECK_CFX_IO(nerr);
      return false;
    }

  }
