           This doesn't compile with g++ 2.95.2:
           test.cpp:9: `operator *' not defined
           but does core dump with edg 2.42

This is actually a problem with the valarray constructor that takes a gslice as an argument, which is called by the valarray::operator[] ( gslice );. in fact, the following code would cause the core dump:

------

#include <valarray>

int main()
{
std::valarray<double> dval;
dval[std::gslice()];
}
