[RESOLVED] Segmentation Fault

[originalmoose]

Hopefully this should be an easy problem I have looked all over my code and I cannot find where the problem lies. The program reads to large ints from a text file adds them and then outputs the result. Ive included the code below.

int main()
{

        bigint a, b, c;
        std::ofstream outfile("results.txt");
        std::ifstream infile("data1-1.txt");
        if(infile.is_open())
        {
                std::cout << "file open \n";
                while (infile >> a)
                {
                        infile >> b;
                        std::cout << a;
                        std::cout << b;
                        std::cout << "+__________________________________________\n";
                        c = a + b;
                        std::cout << c;
                }
        }
        else std::cout << "Unable to open file\n";

        outfile.close();
        infile.close();
        return 0;
}

and here is the file it is reading from

1123215504550654654648632143546546440808844113546654696870324465406587305476857035744424554321649523187432184732416847321;

3216654832155555151321;

654448798765213211154654521035421556543324432153214463;

65444068465406540065400666554448779873544321115674877635413246543214;

This is a simple ADT exercise the input operator will read until the semicolon. The program works fine without reading from the file in a loop, but that is a requirement for this assignment.

Any help would be greatly appreciated
