boost filesystem crash

[Andrey Batyiev]

I'm using Ubuntu 16.04.

I'm trying to compile simple program using boost::filesystem:

#include <iostream>

#include <boost/filesystem.hpp>

namespace boostfs = boost::filesystem;

int main(int argc, char **argv)
{
    boostfs::path p = boostfs::path("/tmp/test/test2.txt").parent_path();

    std::cout << p.native() << std::endl;
    return 0;
}

However it crashes:

==3548== Invalid read of size 1
==3548== at 0x4E49793: boost::filesystem::path::m_parent_path_end() const (in /usr/lib/x86_64-linux-gnu/libboost_filesystem.so.1.58.0)

It seems there is a bug in the boost filesystem package.
