Internal compiler error in g++ 2.95.2

[Joel Yliluoma]

An error appeared while I was trying to compile one complex program.

For your convenience, I made a short test program which
only contains the piece that causes the bug message.

Ask me if you need anything else than what is in this message.

I attached the resulting preprocessed file for investigation.
The full sourcecode is here:


class track
{
public:
    unsigned dummy;

    track split(unsigned row)
    {
        track first, second;

        for(unsigned a=0; a<dummy; ++a)
            if(a < row)
                first.addrow(*this, a);
            else
                second.addrow(*this, a);
        *this = second;
        return first;
    }

    template <class T>
    void addrow(T &pat, unsigned row)
    {
        row = *"Idea: I have a class named pattern"
               "and a class named track, and there"
               "would be two routines, addrow for"
               "track and pattern, looking exactly"
               "identical. Let's shorten it up."
               "(This message was added here for the bug report only.)";

        dummy = pat.dummy;
    }
};

int main(void)
{
}
