Weird g++ error with current 3.4 CVS

Weird g++ error with current 3.4 CVS

[Richard Guenther]

Since a g++ rebuild of todays CVS I get the following weird error from 
compiling the POOMA library:

/net/alwazn/home/rguenth/src/pooma-bk/r2/src/Domain/SliceDomain.h: In 
method `SliceDomain<DomainTraits<SliceRange<2,1> > >::SliceDomain(const 
SliceDomain<DomainTraits<SliceRange<2,1> > > &)':
/net/alwazn/home/rguenth/src/pooma-bk/r2/src/Domain/SliceRange.h:121: 
instantiated from `SliceRange<2,1>::SliceRange(const SliceRange<2,1> &)'
/net/alwazn/home/rguenth/src/pooma-bk/r2/src/Engine/BrickBase.cpp:301: 
  instantiated from `Pooma::DoubleSliceHelper<1,2>::init(Interval<1> &, 
int *, int &, const Pooma::BrickViewBase<2> &, const SliceInterval<2,1> &)'
src/Engine/BrickBase3.cmpl.cpp:38:   instantiated from here
/net/alwazn/home/rguenth/src/pooma-bk/r2/src/Domain/SliceDomain.h:156: 
non-constant `operator <=<DomainTraits<SliceRange<2,1> >::{anonymous 
enum}>((+&sliceDimensions), (+&dimensions))' cannot be used as template 
argument

where it is moaning about the CTAssert in

   // copy constructor
   SliceDomain(const SliceDomain<DT> &sd)
     : slice_m(sd.slice_m),
       domain_m(sd.domain_m) {
     CTAssert(DT::sliceDimensions <= DT::dimensions);
     for (int d = 0; d < DT::dimensions; ++d)
       ignore_m[d] = sd.ignore_m[d];
   }

where CTAssert is defined in the usual way

#define CTAssert(c) PoomaCTAssert<(c)>::test()

template<bool B> struct PoomaCTAssert {};

template<> struct PoomaCTAssert<true> { static void test() {} };

and DT::sliceDimensions and DT::dimensions are anonymouns enum entries. 
  It seems DT::sliceDimensions <= DT::dimensions is treated as method 
reference somehow, is this correct or even standard conform?

g++-3.4 (GCC) 3.4.2 20040816 (prerelease)

Whoops, sorry.  A g++ 2.95 slipped under my mpiCC.
