I'm running g++ 2.2.2 on a SPARCstation ELC under SunOS 4.1.2.
The following C++ code, which redefines a method of a templated
class, causes cc1plus to get signal 11:

template<class T> class a{
public:
    void foo(int);
private:
    T v;
};

template<class T> void
a<T>::foo(int x)
{
}

template<class T> void
a<T>::foo(int x)
{
}

main()
{
    a<int> zz;

    zz.foo(99);
}

The above file is twice.cc. When I run
g++ -v twice.cc
here's what it says:

I didn't compile cc1plus with debugging turned on, so the backtrace
from the core file isn't very interesting. But here it is anyway:
#0  0x24498 in start_function ()
#1  0xe7bc in yyparse ()
#2  0x7c4e0 in output_file_directive ()
