The code crashes in that function
Basically all the versions of g++ until current 4.0 do not know how to handle
template<typename L, typename R> inline
FExpr<ExprOp< typeof( dx(L()) ),
typeof( dx(R()) ),
Add<typename ResultType<L,R>::Type>
> >
-------------------------------------------------------------
template<typename L, typename R> inline
FExpr<ExprOp< typeof( dx(L()) ),
typeof( dx(R()) ),
Add<typename ResultType<L,R>::Type>
> >
dx(const FExpr<ExprOp<L, R, Add<typename ResultType<L, R>::Type> > >& rF)
{
typedef typename ResultType<L, R>::Type Type;
ExprOp<L, R, Add<Type> > expr_op = rF.GetExpr();
L l_ = expr_op.GetL();
R r_ = expr_op.GetR();
typedef typeof( dx(l_) ) dxTypeL;
typedef typeof( dx(r_) ) dxTypeR;
dxTypeL dxl_ = dx(l_);
dxTypeR dxr_ = dx(r_);
typedef ExprOp<dxTypeL, dxTypeR, Add<Type> > dxOpType;
return FExpr<dxOpType>( dxOpType(dxl_, dxr_) );
}
-------------------------------------------------------------
That is critical for auto-differentiation code; auto/decltype would be an easy
workaround but at the moment typeof is the only option I have here!
