file_descriptor(int,flags) constructor fails

[Dylan Doxey <dylan.doxey@…>]

The following code fails to compile:

int fd = fileno(filename);

boost::iostreams::file_descriptor_source fd_src(

fd, boost::iostreams::file_descriptor_flags::close_handle

);

The compiler reports: ... /usr/include/boost/iostreams/device/file_descriptor.hpp:194:11: error: no matching function for call to ‘boost::iostreams::detail::path::path(boost::iostreams::file_descriptor_source* const&)’

{ open(detail::path(path), mode); }

...

Evidently the templated constructor is overriding.

To clarify, the templated constructor is being selected as the only viable overload.
