gzip_decompressor() Segmentation fault

[woojae-jang]

Hi

Using the boost library, I was trying to read the gzip file. But i faced the Segmentation fault error.

#include <boost/filesystem.hpp>
#include <boost/iostreams/filter/gzip.hpp>
#include <boost/iostreams/filtering_streambuf.hpp>
#include <fstream>
#include <iostream>
#include <string>

using namespace std;
using namespace boost::filesystem;

int main(int argc, char** argv)
{
    boost::iostreams::filtering_streambuf<boost::iostreams::input> inbuf;
    inbuf.push(boost::iostreams::gzip_decompressor());

    return 0;
}

Segmentation fault (core dumped)

i used boost 1.79.0 with conan on Ubuntu 20.04.3 LTS

I have posted the same question on stackoverflow.

Another data point: I tried your program with boost trunk on Mac OS 10.15.7, and it ran w/o any problem.

I am facing the same issue with boost 1.81.0. Did you finally resolve it?
