wrong error message for program options with dashes

[thomas.zuhl@…]

Hi, I defined some options:

optionsDescription.add_options()
     ....
    ("output-file,o", program_options::value<std::string>(), "Result file")
     ....;

Now, when I start my program without an argument (e.g. ./myprog -o) the error message says:

the required argument for option '--file' is missing

instead of

the required argument for option '--output-file' is missing

This worked at least with version 1.48.

I can reproduce this issue with boost 1.53.

Using a small example (cf. attachment):

./minipo --foo-1 dd 
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::program_options::invalid_option_value> >'
  what():  the argument ('dd') for option '--1' is invalid

Where the options are defined as:

./minipo --help    
Options:
  --help                this help screen
  --foo-1 arg           foo
  --bar-2 arg           bar
