printf上的分段错误-NASM 64bit Linux

我尝试使用输入四个浮点数scanf，将它们存储到堆栈中，然后使用vmovupd将它们复制到寄存器中以供使用。我的问题是，当我尝试输出这4个数字时，程序seg错误出现在printf。

我认为它与堆栈有关，但是我尝试多次弹出（一次执行多个指令）无济于事。我还是汇编编码的新手，所以使用gdb它对我来说有点太先进了。

您会注意到我包含了一个名为的文件debug。它使我能够查看寄存器和堆栈（这就是为什么要有dumpstack指令的原因。）这是由我的教授提供的，它确实提供了一些帮助，但显然还不够（或者也许我只是缺少了一些东西）。

这是.cpp：

#include <iostream>

using namespace std;

extern "C" double ComputeElectricity();

int main()
{
    cout << "Welcome to electric circuit processing by Chris Tarazi." << endl;
    double returnValue = ComputeElectricity();
    cout << "The driver received this number: " << returnValue << endl; 
    return 0;
}

这是ASM代码：

%include "debug.inc"
extern printf
extern scanf
global ComputeElectricity
