[asio] attempt to copy-construct an iterator from a singular iterator

[Dmitry Goncharov <dgoncharov@…>]

The following program triggers an assert in the debug mode of gnu stl.

dgoncharov@localhost ~/asiobug $ cat main.cpp

#include <unistd.h>

#include <boost/asio/io_service.hpp>

#include <boost/asio/posix/stream_descriptor.hpp>

int main()

{

boost::asio::io_service ios;

boost::asio::posix::stream_descriptor sd(ios);

}

This following thread contains answers. I have the same problem with 1.40. It is a pity that the debug mode is not used during testing.

This is a duplicate of #3098, which is fixed in 1.40.0. I have confirmed that the attached test case does fail with 1.39 but does not with 1.40.

If there is a failure with 1.40 then please raise a new ticket with a new test case.

If you care about the _GLIBCXX_DEBUG debug mode then feel free to run the automated boost regression tests in that configuration.
