C++ &引用；已释放对象的校验和不正确；在图书馆'；s析构函数

我试图对音频信号的各个部分进行一些测量（读作

std:：vector

），这涉及到一些信号处理。我使用与中相同的函数计算MFCC常量，但不是使用

Aquila:：SineGenerator

而是使用向量创建

Aquila:：SignalSource

删除无关代码后，我的功能是：

void measure(std::vector<double> &output_vector, std::vector<double> &audio, int start_index, int end_index) {
    // Copy the raw note over.
    std::vector<double> note_audio(end_index - start_index);
    std::copy(audio.begin() + start_index, audio.begin() + end_index, note_audio.begin());

    // Calculate the MFCC constants.
    Aquila::SignalSource input(note_audio, 44100);
    Aquila::Mfcc mfcc(input.getSamplesCount());
    auto mfccValues = mfcc.calculate(input);

    // Copy them over to the output vector.
    for (int i = 0; i < mfccValues.size(); i++) {
        output_vector.push_back(mfccValues[i]);
    }
}

因此，我启动lldb并进行调试，在

malloc\u error\u break

处设置一个断点，并获得以下堆栈跟踪：

开始，通常似乎涉及析构函数。我遇到过类似的错误，这是由于试图返回基于堆栈的变量（oops-这就是我传入输出向量并在函数中修改它的原因），但我在这里看不到这一点-我正在使用它，然后将
double
值复制到我的输出向量。我试着用
new
创建
note\u audio
作为指针，我试着在堆栈和堆上创建一个数组而不是
std:：vector
，但都没有效果

使用CMake和LLVM在OSXMavericks上构建C++11。根据评论中的建议，我保存了的要点（尽管它一直持续到>100个错误）。我在这里遗漏了什么？
我将这个问题发布到Aquila GitHub问题页面和图书馆的创建者那里。为了发现（好时机）

简而言之：Aquila使用的FFT库OOURAFT要求向量大小为2的幂，但如果不是这样，它不会抱怨，它只是在第一次调用
OOURAFT:：FFT（）
时写入释放的内存。外卖课程是在堆上发疯之前始终声明需要检查的条件。
提示：您只需编写
std:：vector note\u音频（audio.begin（）+start\u index，audio.begin（）+end\u index）并且不需要进行复制，也不需要所有那些默认构造。您使用的是什么平台、编译器等。valgrind在您的系统上可用吗？如果是这样，运行它来获取有关内存滥用的详细信息。@DaleWilson:菜鸟错了，对不起！使用CMake和LLVM在OSXMavericks上构建C++11，我听说Valgrind没有在Mavericks（）上工作，但也许是这样？(). 我会看看我是否能让它工作并报告回来。@DaleWilson:我运行了Valgrind，得到了很长的输出，看起来有很多错误（尽管我不知道如何解释它们）。前300行左右就是这个要点。我知道
地址0xa4a050是大小为25200 alloc'd的块后的0字节
通常指25200长度向量上25201位置的写入，但我不确定我在哪里指定了错误的长度。可能您的索引超出了输入向量的范围？
