#9006: read_xml segfaults if run from boost::asio::spawn
-----------------------------------------+---------------------------
Reporter: Mátyás Végh <matyas.vegh@â¦> | Owner: cornedbee
Type: Bugs | Status: new
Milestone: To Be Determined | Component: property_tree
Version: Boost 1.54.0 | Severity: Problem
Keywords: |
-----------------------------------------+---------------------------
I've noticed that if read_xml is run through a boost::asio::spawn then
read_xml encounters a segmentation violation.
{{{
#include <boost/property_tree/ptree.hpp>
#include <iostream>
#include <boost/property_tree/xml_parser.hpp>
#include <string>
#include <sstream>
#include <boost/asio.hpp>
#include <boost/asio/spawn.hpp>
void read() {
std::cout<<"starting read()"<<std::endl;
std::string xml = R"phi(<?xml version="1.0"?>
<start></start>)phi";
std::stringstream ss(std::move(xml));
boost::property_tree::ptree pt;
boost::property_tree::read_xml(ss, pt);
std::cout<<"ending read()"<<std::endl;
}
int main() {
boost::asio::io_service ios;
boost::asio::strand mystrand{ios};
read();
boost::asio::spawn(mystrand,
[](boost::asio::yield_context){read();});
ios.run();
}
}}}
The code above produces
{{{
starting read()
ending read()
starting read()
Segmentation fault
}}}
Compiled with gcc-4.8.1 and clang-3.3 (release) on Suse Linux 11 x86_64.
