[Bug c++/29518] New: incorrect "

["wb at fnal dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

Regression from gcc 3.4.4; under gcc 4.1.1 it produces the diagnostic "error:
'N<int>::okay' is not a valid template argument for type 'bool' because it is a
non-constant expression" -- and I am informed (by gdr) that the bug is still
present in gcc 4.2.0.

The code below makes use of the Boost library; I can also provide the
preprocessed version of the same code, if requested, but it's on the order of
1000 lines long:


#include "boost/mpl/assert.hpp"

template< class T >
  struct N
{
  static  bool const  okay  = true;
  BOOST_MPL_ASSERT_MSG( okay, message_goes_here, (T) );
};

int
  main()
{
  N<int>  n;
}
