[Benjamin Kosnik <bkoz at redhat dot com>]

this is a new static fail since last week, when the new call frame
exception handling bits went in.

21_strings/element_access.cc

  // const_reference at(size_type pos) const;
  csz01 = str01.size();
  cref cref3 = str01.at(csz01 - 1);
  VERIFY( cref3 == 'a' );
  try {
    cref cref4 = str01.at(csz01); 
    VERIFY( false );  <---as soon as try block entered, kabooom
  }
  catch(std::out_of_range& fail) {
    VERIFY( true );
  }
  catch(...) {
    VERIFY( false );
  }
