https://svn.boost.org/trac10/ticket/8843 <p> When a defect string ("\d<a class="report" href="https://svn.boost.org/trac10/report/4">{4}</a> [") is compiled to be a sregex, then an assertion fails, instead of an exception being thrown. This is only in debug mode: in release mode, an exception is thrown as expected. </p> <p> The full error message: </p> <pre class="wiki">Assertion failed!
