Compiling simple Boost Process code fails

Question

I'm trying to implement a platform-independent function (working on Windows/Linux/Mac OS X) for calling an external process using boost/process.hpp as follows:

#include <sstream>
#include <boost/process.hpp>

std::string execute_external_process(const std::string &command,
                                     const std::vector<std::string> &arguments) {
    boost::process::ipstream out;
    boost::process::child child(boost::process::search_path(command), arguments,
                                boost::process::std_out > out, boost::process::std_err > out);
    std::stringstream process_output_builder;
    std::string line;
    while (child.running() && std::getline(out, line) && !line.empty()) {
        process_output_builder << line;
        process_output_builder << "\n";
    }

    child.wait();

    return process_output_builder.str();
}

However, I'm getting the following Boost compilation error:

I cut the remaining error message off since it is quite lengthy. Since my code seems to look fine I wonder if this is a bug in Boost. I'm using the newest version 1.75.0 but this problem also occurred in version 1.74.0 (hence the reason why I updated).

Any ideas on how this could be fixed?
