我遇到了一个向导的范围检查错误，我遇到针脚问题。我正在一个非常大的c ++框架中工作，这个框架设计得不是很好。 Python被用作一个UI，然后调用c ++函数/类来完成所有繁重的工作。所以我运行的实际命令是'python thing.py --option1 etc ......'。有一个函数返回它通过向量中的索引找到的对象。它可以根据设置的bool使用两个向量。更具体地说，我有类似的东西：
object getObject(int i, bool trig=false){
if(trig) return vector1.at(i);
return vector2.at(i);
}
问题在于向量的长度不同，所以如果你给它指错了，或者你忘了设置'trig'bool，那么你很有可能超出范围。这个函数或类似的东西在许多不同的文件中被调用了数千次，所以我很难找到这个范围检查错误实际来自哪里。目前我一直在评论代码块，或者在打印出来之前试图找到代码在崩溃之前的位置，但考虑到我必须这样做的地方数量，这是非常困难的。
当我得到范围检查错误时，是否有一种简单的方法可以打印出调用此函数的位置？堆栈跟踪或类似的东西？我对这类事情并不熟悉。
更新 我尝试过使用GDB命令，如：
gdb -ex r --args python fakes.py --datasets data --dir outdir
我看到同样的错误，我总是得到这样的错误：
Traceback (most recent call last):
File "fakes.py", line 299, in <module>
main(options,args)
File "fakes.py", line 240, in main
driver.submit(job, submitDir)
Exception: void EL::Driver::submit(const EL::Job& job,
const string& location) =>
DataVector::at range check (C++ exception)
然后它让我进入GDB命令行。如果我输入bt（这似乎是获得堆栈跟踪的正确命令），我会收到消息“No stack。”
我也试过用这个命令运行Valgrind，但我没有看到任何有用的东西。因为我是valgrind的新手，所以我可能会错过一些东西。以下是出现错误的valgrind输出：
