GiNaC expressions in stl set

27 Feb 2004


      Hi,

there seems to be a problem with the stl set container:

int main()
{

GiNaC::symbol u1( "A" );
GiNaC::symbol u2( "B" );

std::set<GiNaC::symbol> spec;
spec.insert(u1);
spec.insert(u2);
spec.insert(u3);

std::set<GiNaC::symbol>::const_iterator s1 = spec.find(u1);
// s2 still points to u1 !
std::set<GiNaC::symbol>::const_iterator s2 = spec.find(u2);

GiNaC::ex f = pow((*s1),2) + (*s2) + 200*(*s1);
std::cout << "f= " <<  f << std::endl;

}
