11914	abort is called while boost::filesystem::copy tries to throw and exception	jpo38 <jean.porcherot@…>	Beman Dawes	"Im"" using boost 1.60 with Visual Studio 2015 WIN64. Compiled boost simply by running:

    bootstrap.bat
    tools/build/b2 toolset=msvc-14.0 --build-type=minimal --link=static stage

Now, I get a specific situation where abort is called while boost::filesystem::copy tries to throw an exception. Note that other boost::filesystem functions successfully throws.

This code:


{{{
#include <boost/filesystem.hpp>
#include <boost/filesystem/operations.hpp>

#include <iostream>

int main( int argc, char* argv[] )
{
    // Stepping to folder:

    try
    {
        boost::filesystem::current_path(""B:/dev/msvc2015/vobs_bci/public/tst/base/cppunit/utlfile"");
        std::cout << ""Worked"" << std::endl; // works OK
    }
    catch (...)
    {

    }

    // test throwing upon copy_directory because dource folder does not exist:

    try
    {
        boost::filesystem::copy_directory(""s"", ""b"");
    }
    catch (...)
    {
        std::cout << ""Caught"" << std::endl; // works OK
    }

    // test throwing upon copy because target file already exists:

    try
    {
        boost::filesystem::copy(""./test.h"", ""./copied.cpp""); // works
        boost::filesystem::copy(""./test.h"", ""./copied.cpp""); // should throw and be caught
    }
    catch (...)
    {
        std::cout << ""Caught"" << std::endl; // never reached...
    }

    std::cout << ""Done"" << std::endl;

    return 0;
}
}}}

Outputs:


{{{
Worked
Caught
}}}

And then aborts...
