The error is in MulExp::semantic. It happens no matter if the multiplication
expression is in a template. These are the combinations that fail:

IF / ifloat
IF / IF
ID / idouble
ID / ID
IR / ireal
IR / IR


Here's a sample:

import std.stdio;

typedef ifloat IF;
typedef idouble ID;
typedef ireal IR;

template PrintAddedType(X, Y)
{
    void PrintAddedType()
    {
        X x;
        Y y;
        writeln( typeid( x ), " ", typeid( y ), " ", typeid( x / y ) );
    }
}

template PrintAddedType(X)
{
    void PrintAddedType()
    {
/*
        PrintAddedType!(X, ifloat)();
        PrintAddedType!(X, idouble)();
        PrintAddedType!(X, ireal)();
*/
/*
        PrintAddedType!(X, IF)();
        PrintAddedType!(X, ID)();
        PrintAddedType!(X, IR)();
*/
    }
}

void main()
{
/*
    PrintAddedType!(IF)();
    PrintAddedType!(ID)();
    PrintAddedType!(IR)();
*/
    IR x;
    IR y;
    writeln( typeid( x ), " ", typeid( y ), " ", typeid( x / y ) );
}
