required std::gslice::operator=() declared private
--------------------------------------------------

                 Key: STDCXX-306
                 URL: http://issues.apache.org/jira/browse/STDCXX-306
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 26. Numerics
    Affects Versions: 4.1.2, 4.1.3
         Environment: All
            Reporter: Martin Sebor
         Assigned To: Martin Sebor


The well-formed program below fails to compile because the gslice assignment operator is inaccessible:

$ cat x.cpp && make x
#include <cstddef>
#include <valarray>

int main ()
{
    std::valarray<std::size_t> va;
    std::gslice gs (0, va, va);
    std::gslice_array<std::size_t> gsa = va [gs];
    gsa = gsa;
}
gcc -c -I/build/sebor/dev/stdlib/include/ansi -D_RWSTDDEBUG    -D_RWSTD_USE_CONFIG -I/build/sebor/dev/stdlib/include -I/build/sebor/gcc-4.1.0-11s/include -I/build/sebor/dev/stdlib/examples/include  -pedantic -nostdinc++ -g  -W -Wall -Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long   x.cpp
