[prog] C++ class counstruct problem

[E!]

Hi I been trying to run this following program. But it gives me a weird
error: "asemetric.cpp:16: type specifier omitted for parameter `
Internal compiler error: Error reporting routines re-entered.
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions."

Can anyone please tell me where did I go wrong in this program? I am new
to C/ C++


#include<iostream>
using namespace std;

class vehicle
{
        public:
                vehicle (char name, char model);
                void print();
        private:
                char car_name;
                char car_model;
                void testcar();
};

int main (int argc, char*, argv[])
{
                vehicle a("Toyota", "Corolla", 1990);
                vehicle b("Nissan", "Sunny", 1994);
                vehicle c("Mercedes-Benz", "550", 1990);

                cout << "Original Statistics: " << endl;
                cout << "=====================" <<endl;

		a.print();
                b.print();
                c.print();

		return (0);
}

vehicle::vehicle(char name, char model)
        :car_name(name), car_model(model)
{
        testcar();
};
