operator-() for valarray

[Takanori YOSHIKOSHI]

Hi,

I can't compile the following program with gcc-2.95.2 and
libstdc++-2.90.7.

// tmp.cc
#include <valarray>

using namespace std;

int main()
{
  valarray<int> v(1, 3);
  - v;
}

$ g++ -I/usr/local/include/g++-v3 -L/usr/local/lib tmp.cc
/usr/local/include/g++-v3/bits/valarray_meta.h: In instantiation of `_UnClos<negate,_ValArray,int>':
/usr/local/include/g++-v3/bits/valarray_meta.h:643:   instantiated from `_Expr<_UnClos<negate,_ValArray,int>,int>'
/usr/local/include/g++-v3/bits/std_valarray.h:553:   instantiated from `valarray<int>::operator -() const'
tmp.cc:9:   instantiated from here
/usr/local/include/g++-v3/bits/valarray_meta.h:339: no type named `result_type' in `class _UnBase<negate,valarray<int> >'

Is that a bug?

Best regards,
