[Bug libstdc++/14254] New: Problems with masked valarrays

["schmid at snake dot iap dot physik dot tu-darmstadt dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The masking facility of valarrays does no longer work. gcc 3.3 and earlier
versions of gcc 3.4 have no problems compiling the appended code tmv.C.

Source code tmv.C

#include <valarray>

using namespace std;

int main()
{

    valarray<double> va(5);

    for (int i=0; i<5; i++) 
	va[i] = i;
    
    va[va>2.0 && va<5.0]
        = valarray<double>(va[va>2.0 && va<5.0]) + 42.0;
}
