[ghost]

Package and Environment Details

• Package Name/Version: boost/all
• Operating System+version: Linux Ubuntu 20.04
• Compiler+version: GCC 10

Steps to reproduce

The below code with a standard boost install, always produces an empty stacktrace because BOOST_STACKTRACE_USE_NOOP is always defined.

#include <iostream>
#include "boost/stacktrace.hpp"


void f3()
{
  std::cout << "********** Start backtrace **********" << std::endl;
  std::cout << boost::stacktrace::stacktrace() << std::endl;
  std::cout << "********** End backtrace **********" << std::endl;
}

void f2()
{
  f3();
}

void f1()
{
  f2();
}


int main()
{
  f1();
  return 0;
}
