https://svn.boost.org/trac10/ticket/8009 <p> When using a long option with a <strong>hyphen</strong> in its name, the error string does not output the option name, but rather the substring from the rightmost hyphen position. </p> <p> Example: option foo-bar with double. </p> <pre class="wiki">./myprogram --foo-bar nonumber </pre><p> Since "nonumber" cannot be cast into double, it throws an exception. The error message is: </p> <pre class="wiki">"the argument ('nonumber') for option '--bar' is invalid" </pre><p> Option name is wrongly quoted as <strong>"--bar"</strong>. Expected is <strong>"--foo-bar"</strong>. </p> <p> Check the attached example for reproduction. See the attached patch fixing the bug.
